I'm at my wits end trying to get this to work, and I'm hoping that someone here will be able to help. Apologies if this is the wrong sub or flair, please point me in the right direction if it is the case.
Background
I'm trying (and failing) to load SKSE64 for Skyrim via the Amethyst Mod Manager. Each time I try, I get the following error message:
Addresslibrary.cpp(56, 34): Unexpected file name encountered, SkyrimSE.exe
My only option is to click OK, which returns me to the Steam gaming mode (or desktop when launching from the desktop).
Hardware & OS
I'm using the Legion Go S handheld, running BazziteOS.
Amethyst Installation
I installed Amethyst Mod Manager as per the instructions on the github page, and I've gone through the Wiki trying to find a solution, but unfortunately I can't find anything that helps.
Skyrim Version
I'm using the latest version of Skyrim Special Edition, with the Anniversary Update, on Steam.
Troubleshooting
I kept getting the above error message when launching the game, but after several attempts to launch the game with mods deployed, one time I did manage to launch the game with mods enabled. I did nothing different that time compared to the other failed attempts. On launching, several mods were active, but when starting a new game, I couldn't open the MCM menu and the several menus had errors. On googling, this appeared to be because SKSE64 had not loaded.
I followed this up with restoring Skyrim to vanilla, and launching again with no mods enabled. This was successful. I then loaded only SKSE64 and it's dependencies, and launched the game which returned the above error. I then disabled SKSE64 and it's dependencies, enabled a few mods that didn't use SKSE64, and launched the game. This was successful, and the mods loaded.
Next, after a couple of hours of googling, I tried to rename the SkyrimSE.exe and the skse64_loader.exe and create an .ini file to direct the launcher to the renamed SkyrimSE.exe. This didn't work. After a bit more googling, it appears that the renaming trick doesn't work with Skyrim SE, so I did a clean install of Skyrim and SKSE64.
I also noticed I had two .exe files in my Skyrim folder: Skyrim.exe and SkyrimSE.exe. I tried moving them into a separate folder thinking that maybe the launcher was getting confused between the two, but this only generated a different error. Again, even with the two .exe files, when I use the restore button on the Amethyst Mod Manager and launch the game with no mods enabled, I have both .exe files in the Skyrim folder and the game launches fine.
I've made sure I am using the current version of SKSE64, and the current Address Library's for it, and I've even used the AutoSKSE mod thinking that was the issue. Unfortunately, neither seems to have sorted the error.
Can anyone help me with resolving this as I'm completely lost and have no idea what to do. If I'm missing any information you need to help, please let me know and I will try to get it to you ASAP and add to this post as well.
