I want to save a PDF file but the keyboard generates other letters

I want to save a PDF file, but when I press one keyboard appears another letter or number. I don't understand because the keyboard is working with other applications.

I saw this happening a couple of times as well (not just in Acrobat). It's very strange.

It usually gets fixed by itself if you switch to another application and then return to the original one and try again.

I have the same problem, just started today. I cannot figure out what is wrong. Keyboard works correctly with all other programs.
