Game launches and plays fine on first launch, but doesn't launch the game at all the second time or after. Requires game reinstall to launch again.

The game launches perfectly fine once, no issues with the game itself. However, when I try to launch the game after that first launch, it never launches. The game shows up on my task manager but never shows up in any way on my computer otherwise. When I click Play after again, the launcher tells me the games already running. I've tried repairing the launcher and doesn't seem to fix. Only way I've found to fix it is by completely reinstalling the launcher. (Note I have mods installed but it does it with vanilla anyways)
