Why is the font not installed in Windows 10?

Question

Fonts

It gives the error "The requested file is not a font".
On the microsoft site this problem is described and a solution is given - turn on the firewall and security center services ... And many noted that this solved their problem. My problem is that I have these services turned on all the time. To hell with it, restarted. Then stopped and started. Nothing helps.
How to be something? ..
PS: the problem is only with some fonts. Who can, please look at this file:

(ttf icon font file, 43kb)
Does it open for you? Maybe it's not in Windows.
