Fonts are not installed and opened on the PC, there are reasons why?

Question

Fonts

Hello, friends!
The other day I was overtaken by a misfortune, I would not say that it was very critical, but rather unpleasant and annoying. The fact is that on my computer the fonts (TTF, OTF) are no longer displayed in the thumbnail and now they can not be installed as before with the right mouse button, that is, the word "Install" has disappeared altogether, there is only one installation option left - just drag them to the folder with fonts and it's damn inconvenient. Probably spent a day trying to figure it out, tried to google, without success at all, I don’t understand what’s the matter. By the way, when I try to open the standard program "fontview.exe", it writes to me that: "The requested file is not a file font" and does not associate with this executable either.

If anyone has had a similar experience, or has any thoughts at all, please share, I would be grateful.
