Windows 10: Weird glitch

Hello today my uncle gave me a PC yes it is Windows. There were 2 games, call of duty and another call of duty it were the same games. The first one was Russian same as the other one. When I oppend the first Russian call of duty everything was normal. But when I opened the second one it asked me"Are you sure you want to open this game? wner unknown " and after I pressed "Yes" an error message showed up with random symbols and I thought it was a virus or is this part of the Microsoft program?

Tried both things. The troubleshooter said there were no problems. Uninstalling the keyboard device also did not work. The weird thing is even after I uninstalled the keyboard device, the glitch keeps happening even though my keyboard doesn't work and
I can't type. And the problem is definitely not the mouse.

The problem has been resolved. Everyone who tried to help me were overthinking the problem, including me.

All I literally had to do was pull the power plug on my computer's PSU, then plug it back in and the glitch was fixed.

This seems like a very weird bug with Windows 10, definitely a software problem that should be reported.
