Hi, again.
I wanted to edit my previous report, because I noticed smth new about the problem. I fall immediately, after trying to stand up from a "crawling mode". Each time I accidentally, or in need press Crawl, it ends the same. I can't stand up after that. If I try, the falling starts immediately on the same place.
I discovered that I can disable it by interacting with computer or console screen, while crawling. After that I just press esc and character stands up, with ability to walk normally again. But still, with that problem I can't use "Crawl" anywhere.
And no, there's no sick or hungry notifications.
