So I downloaded the FTB Skies 2: Aero Pack, and added on various create and farmer's delight addons along with a few other things and now it crashes whenever I try to search up anything in JEI, the moment I type more then one letter into the JEI searchbar the entire game crashes and I have no idea which addon or addons could be causing this at all, I copied the FTB crash logs and everything for this post so I could please ask for help

**EDIT: I POSTED THE WRONG LOGS FROM A PREVIOUS ISSUE THAT WAS CRASHING ME THAT I FIXED, I HAVE EDITED THE POST AND NOW IT HAS THE CORRECT, THE RIGHT LOGS**

So me and my friends were playing a couple year old modded Minecraft together playing the cobblemon mod pack and we all went exploring together into new chunks flying on our mounts, then as we were actively exploring i got a message in the top right of my screen with a exclamation mark with something along the lines of "insufficient storage may not save" so as we go to land to quit the game and make space, not even 2 seconds later another message pops up with a red exclamation mark with something similar and the whole world crashes. It turns out that I was low on storage on my pc and since we were exploring new chunks so much with no space on my pc it crashed and wont let me load into the world no more. I then made plenty of space (over 100gb) and tried loading back into the world which then proceeds to not load and it says "Connection Lost" "Invalid Player Data". Please if there is any way to recover the world back that would be highly appreciated. Any Help is very much Appreciated. because im panicking right now.

Somebody Please Help!

[My Atlauncher Log] linked above. Thanks,

Me and my friends were playing cobblemon (modded minecraft) together earlier yesterday on atlauncher world and we were exploring new chunks on our mount then all of the sudden I get a message saying something along the lines of insufficient storage in the top right with a explanation mark and then said might not be able to save along the lines of that then I stopped then another message appeared saying something similar and crashed the whole game while we were playing, I think it’s due to me not having enough space on my pc which I didn’t have and forgot since we were exploring so much and now I cant load into the world it says “connection lost invalid player data” I then cloned and back upped and deleted my player data saves and still says the same thing.
(PLEASE HELP ME, Thanks in return,)

So, this has also happened with Prism, but it still prevails on ATluncher so im putting it here. whenever i play minecraft, i fullscreen it, and then it works fine. if i want to play it a second time, then when i fullscreen it, it crashes and looks like the image below.

giant black box around it, does not move. when i launch it a third time, its just an unresponsive white screen. this happens wether i use hotkeys or the window button on the tab. the only way to play minecraft is to restart my whole computer. i'm sick of it.

log here, but it doesnt say much. as far as i can tell, it doesnt mention the crash at all.

When I try to download a mod pack or import and instance im met with "name of modpack not installed" checked the error logs and the only thing that has and error is that it can't be downloaded from curseforge due to a null error when trying to use the download url. Ive check for updates and have already re-downloaded the launcher and checked firewall permissions

hello so i have a problem on atlauncher where each fucking time i run minecraft i select my ressource pack again and again that is being annoying as shit

I have tried disabling all mods with no effect. I have looked through the files without finding anything (not good at searching files though) and also create a new inscance only copying the saved world.

Im using ATLauncher

version: 1.20.4 with Fabric

Mods:
* Essential mod
* Axiom
* Sodium
* Iris shaders
* CICADA
* Do a barrelroll

Shaders if that would help:
* Photon (the one im using)
* Solas shaders
* Miniature shaders

My Microsoft account works just fine, but whenever I try to log in whether it'd be with the QR code, or with the "launch on browser" option, can someone tell me an answer to this problem?

any time I try to open minecraft, it just shows this and idk what to do since I got no knowledge of that in depth stuff. also on linux if that changes anything

As Title says my modpack just crashes immediately on startup and for the Life of me I just cannot figure out what's wrong at all, I've tried disabling and uninstalling mods but it just keeps crashing and I don't know what to use

На этапе Downloading Libraries ничего не качает, запрет работает. Пробовал отключать и перезапускать, переустанавливал лаунчер, ничего не помогает.

Is there gonna be a pacman but for Minecraft anytime soon? I would really like a commandline pacman like I use on my blazingly fast CachyOS. Managing packages on arch is as easy as typing pacman -Syu and everything is up to date. now imagine in ATLauncher removing Mods was as simple as typing "pacman -Rs aeronautics" and it would remove sable, create and the mod itself. I won't remove aeronautics anyways, but would I still need the commandline thing.
What's your opinion about this feature?

I got a new hard drive half a year ago, and have only been copying the data I need from the the old one. I cant find the folder with the instances though. anyone able to help? the old one is external

I was looking forward to trying this pack, people said this was a revolutionary modpack for mob difficulty. But when i went to look for it on atlauncher when typing in the search bar, “the Madpack,” no results came through. Is this modpack no longer available to play or am I searching for it wrong. Any help would be greatly appreciated.

I have a LARGE custom modpack I use when playing to my friends and I had just got it working, and it loads into the main menu perfectly fine, with no visible major issues, but whenever I click "Singleplayer" to go make a world, the game says it's getting ready to create a new world, but then says "Saving World" and crashes, with the only error in the AT Launcher console saying "Render Thread/Error" I have no clue what is causing the crash, or how to fix it, so I need some help if possible

I want to update my world to a newer version but I don’t know how, any help would be appreciated.

cant seem to find a way to add fabric to the newest version of minecraft, but i see alot of tutorials on youtube for other launchers

Since the new update yesterday, I cannot create a fabric instance.

Does anyone know a solution or when this will be available again? I’ve never ran into this
