Weird hotkey issues in Photoshop and Illustrator?

Question

Adobe Illustrator

I have been using Photoshop and Illustrator for a long time and this is the first time I have encountered such a problem.
Yesterday, for some unknown reason, the hotkey of the "pen" tool fell off in illustrator. I set up some combinations for myself, everything worked fine, I did not change anything. I've been using these settings for a couple of months. And then bam. Nothing was bound to the "P" key. It just fell off. The pen tool was not bound to any key. In general, some kind of nonsense, I could not bind the pen to the standard "P" key at all. Moreover, there was no conflict. I didn't even understand how it was possible. Do not care, reset to default.
Today I open Photoshop, I want to duplicate the layer - it doesn't work. When dragging a layer to a new one, it is created. In short, I realized that hot key combinations that use CTRL do not work. Naturally, the CTRL key itself works. And I didn't change anything either. Everything worked, and then the mysticism began. It was then that I became alert - yesterday I was an illustrator, today Photoshop (although I didn’t open it yesterday, maybe problems started with Photoshop yesterday). I think maybe it's in the products from Adobe? Both programs are not licensed. Guilty.
Actually, the question is: what could be the reason? I don't see the logic between a glitch in Illustrator with a "fell off" pen and not working CTRL in Photoshop.
I remembered that yesterday I disconnected one of the hard drives from my computer, connected it to another PC in order to throw something off. But both programs are on a different hard drive. This one is for information. I have win 10, on another computer also win 10.
Maybe viruses?
