Cant get into options

My brother cant get into his options without his game crashing. He doesnt have an account here so I am asking on his behalf. He has a Microsoft account but not steam. Pease let me know what he can do so that his game doesnt crash when he goes into options.

Maybe he can reinstall the game? Not sure if that would solve the issue.

He did that but didnt work. He also doesnt have it on steam for some reason. its from Microsoft?

Which windows operating system does he have?

Idk to be honest I will ask him but I think windows 10
