Okay. Do you have Wine installed?

Wine can potentially help resolve the .exe and .NET errors that you’re experiencing.

Did you download it via Snaps or Flatpak?

We’re you able to download the game via Steam? And if so, what method did you use to launch it via Lutris? Did you try launching it by accessing a file?

Try looking in: ~/.steam/steam/SteamApps/common

I don’t have BG3 installed, but I have had some weird issues when using Steam lately. Have you tried using Lutris to launch the game?

C’mon peeps…this is Linux Gaming (having fun, playing games and looking for help to get our favorite games to run properly). It’s a community focused on information and support - confrontations and PvP should be reserved for “in-game” experiences only ;).

Another update: I installed the game on a newer computer running a different OS, and BG1 is now working as expected.

It’s interesting, I only have a couple of Steam games in my library, but they all respond differently on my two systems - some that didn’t play, now do. And some that worked on the other system, won’t on the new one 🤷‍♂️.
