I can't make screenshot. F12 doesn't work. I can do it only by clipboard (PrintScreen + Paste).
My version is EPIC/PC.
I have nice screenshots from previous instalation but no one from current.
How to solve this problem?

F12 is the default screenshot key for Steam.
The Epic overlay doesn't provide a screenshot function.

They've added the screenshot function from the main menu.
