I found a fix for this, I moved the main folder from downloads to my C drive, then reinstalled Thunderstore. Not sure which one of these was the main fix but its working now so idrc
Hate to be this guy, but I'm having the same problem and haven't figured out how to fix it. I downloaded the game, extracted it into downloads, and when I try to select the exe when setting the launch location in thunderstore I get this error
