I've recently made the switch from Win11 > Arch mainly due to privacy concerns [Copilot, anyone? No? Don't blame you] and, despite trying throwing everything at the wall, I keep hitting the 'Data validation failed' error.
Currently I'm running it with GE-Proton9-10. I have tried, so far:
- Uninstalling and reinstalling BG3. Twice.
- Trying every. Single. Proton version [this one has had varying levels of "working", some don't launch the launcher at all and some go through but data validation always fails]
- Doing `--skip-launcher` [Steam says it's running, but it quits out after a few seconds]
- Changing the perms to the BG3 directory to `drwxrwxrwx` recursively [this has been the most "progress" so far]
It's weird. I know it's a problem with BG3 itself because I'm able to run games like C2077 just fine [hells, even better than Win11]. I guess it's good my setup's forcing me to take a break from this game considering the 4+ active campaigns I had when I was on Win11 [I have the saves on a flash drive].
I'm willing to do pretty much anything except going back to Win11,
including wiping the computer again and going with a different distro.
