So basically 3 days ago i tried to change my screen resolution for a game called red alert because it kept freezing and i followed some tutorial on yt. After i finished it i can’t open any programs except for like… .exe programs.

I’m trying to open folders.They show up in the windows bar but i can’t enter them. I don’t know if i explained very well since english is not my mother language but please help im desperate because all my work is saved right there and I don’t know what to do. I’m trying to open the task manager but i can’t.
