Heya, so I'm seeing this in the crash dump file:
The thread tried to read from or write to a virtual address for which it does not have the appropriate access```
This unfortunately can be caused by quite a few different things from faulty RAM to permissions issues to incompatible/corrupt drivers to... several other things 😅
The most common cause of the issue it sounds like you've already ruled out by troubleshooting, which is verifying your game files and running Windows' System FIle Checker. Other things you can try to rule out is: antivirus software interfering with Labyrinthine launching, a clean install of your graphics drivers in case old driver files are messing with something or your current install corrupted somehow, run Windows Memory Diagnostic or a third-party tool to test your RAM for errors, and moving Labyrinthine to a different drive if available.
As a last resort you could also try running both Steam and the game as administrator to rule out a permissions issue: close Steam by clicking Steam in the top left -> Exit. Right click Steam on your desktop or search for it and select Run as administrator. Right click Labyrinthine on your desktop (if not on desktop, right click it in your Steam library and browse local files) then run it as administrator.
