I've had the game for about 2 weeks and this past week the game crashes on startup. At first switching from Directx11 to Vulkan worked but now the game crashes on both. I did the verify/repair option on Galaxy which partially works, it allows me to start the game no problem, but without sound. When I exit the game I have to verify/repair option if I want to play the game again. Please help!

Sounds like your system is the issue, not game or galaxy options... Unless you have galaxy or bg3 installed to C program files

Failing to load sound means drivers are out of date or (more likely) auto options are set to high... Try lowering them to medium
