Ok, re-install the game. Find the Strive.exe file from the Debug mod, rename it to "Strive Debug", and copy it into the new Strive program folder next to the Strive.exe. The two .exe have different icons to easily tell them apart. If that does not work, then you either have a bad install of Strive or you do not have 64-bit Windows.
If that works, then you should get 2 windows when running the game. Run the game as you normally would until you get errors in the debug terminal. Post those errors here.
