How to get nVidia Shadowplay to work?

Question

Windows

Good day, gentlemen!
With the new nVidia drivers comes the GeForce Experience application, which, in turn, has such a nice (in theory) thing as Shadowplay. This is a screen recorder with a minimal load on the system and, it would seem, everything is cool, but it does not work. I have an ACER V15 Nitro laptop, OS Win8.1x64, which meets the requirements of Shadowplay, the path for saving temporary files and the videos themselves in Latin, but the recording is not performed. The recording icon, both automatic and manual, is crossed out with a red line. Shadowplay creates folders with names for videos, but nothing is written there. A lot of material was studied on this issue and neither restarting the services, nor reboots at "key points" did not help, I played with the settings as best I could, what to do with it?
