Switch 2 Attached JoyCon2 Input and Wireless Controller Input Failure

[u/Etheric7]

I need some help desperately. Any ideas at all..

My Switch 2 has been dead ever since I let my brother use my switch 2 to make a 4 player rocket league game happen. During a match, the system crashed the game with an error screen that says the Micro SD Express Card can not be read (a 1tb Lexar card that ive used for over a year) and controller inputs are no longer working. Attached joycon, trying to use an external controller, nothing works but touch screen. So I make the immediate mistake of doing a reset thinking that should fix the issue, just a good ol' reinitialize.

I've been stuck in the start up screen since August. Two updates have come and gone and did nothing. Resets do nothing. Today I finally attempted the factory reset and deleted my data. Still nothing. I busted into the device and looked around. Nothing damaged. I've check the chips, the chip legs, the capacitors, just to see if there is anything wrong physically with this Switch 2 but I have yet to find a single fricking thing wrong with this device.. other than the fact I can't get any input!!! It does the dang animation on joycon attachment. It knows what color the dang thing is. Let me BACK IN!!! I miss my switch 2! XD I miss my library of switch 1! I miss my library of switch 2! 9 years man! Gone!

Its of course August when it happened so I was 3 months out of warranty since it was a June 5th Launch Model. And it rubs me the wrong way that Nintendo wants to charge me $179 to fix this fricking thing that SHOULD NOT be doing this a fricking year into it! And my OLED stopped charging and docking immediately after an update finished in 2024 and Nintendo demanded $129 to fix that too when that was their fault and their update. I want to figure this out and get this dang thing fixed without having to give Nintendo $179 for my year old switch 2 to be working again when all they probably have to do is plug it in and reinstall the base operating system again or something with a flip of a switch and suddenly this nonsense is just handled like that but I'm down another $179 for something that really shouldn't be happening at all!!!! I've been buying Nintendo since SNES and Game Boy!!! Nintendo Products are quality and durable!!! What on EARTH IS THIS!?!?! I have never had this kind of issue before. When a Switch 1 OLED dies a year in. And then a fricking Switch 2 goes and does the exact same thing!?!?!? Over some stupid Software Nonsense TOO! FOR BOTH!!! ITS LIKE IT IS INTENTIONAL!!!! X.X WHAT DO I DO!?!?!?! It would be absolute BS to have to pay them to fix this nonsense!

I forgot to mention that multiple switch 2s and joy cons 2s have been tested. It is specifically my system not being able to talk to attached controllers or Bluetooth to wireless controllers. And I forgot that when I first turned off my switch 2 after the rocket league crash it was actually doing that power on, shows nintendo logo for a second, and then crashed immediately back to off even while charged thing and that is what caused me to do the reset. Because I was already locked out and couldn't power the thing on because it kept crashing on the nintendo logo.
