Windows Server 2019 - new user and problem after logging in with the windows explorer

Good morning,

Since yesterday I have been struggling with the problem of adding a new user to the system.

Actually, adding is not a problem, I connect, log in (I have the login information displayed) and then, a black screen and blinking marks on the bottom bar - Windows time and tasks ..... and it can flicker all day long.

Five users added earlier, a few months ago, are logging in and there is no problem. Every new one - has a problem regardless of user or admin rights.

In the processes of the new user (I preview the processes from the administrator level), I can see that the windows explorer is starting, in a moment the info is paused, a new one starts and so on.

Network drives disconnected, recently installed software fired. I do not know when the error occurs because only after the request to create a new user such a surprise came out. I searched the depths of the web, but there is no walkthrough. Slowly, my ideas are running out ... please help.
AV - Windows defender. scf / scannow - done - same. The system is not in a domain. RDP licenses are in sufficient number

Could you show a screenshot for the error? and the log is in another language that I'm not able to read.
