As the title suggests, the game ran previously, but doesn't anymore. The time period between me playing and it not running anymore is about 6 to 8 hours in which I swapped out a faulty SSD drive for a new one and now whenever I try to launch the game, the game is registered as being opened and Proton attempts to run the game, but fails to run the game due to three errors:

1) err:steam:initialize_vr_data Could not load libopenvr_api.so.

2) err:module:import_dll Library mfc100.dll (which is needed by Path/To/GameLauncher.exe) Not Found

3) err:module:LdrInitializeThunk Importing dlls for Path/To/GameLauncher.exe failed, status c0000135

Log ends with; pid 26566 != 26565, skipping destruction (fork without exec?)

Anyone got any tips or solutions? It would be greatly appreciated.
