OpenSSH(7.7&8.1) windows server 2019 standard edition - problem with port 22. How to decide?

Question

OpenSSH

Hello to all.
We use software: OpenSSH(7.7 & 8.1), OS Windows Server 2019 Standard [10.0.17763]
Problem:
From time to time (through random periods) the OpenSSH service “freezes” - stops listening to port 22, in one case telnet just gives a black screen - without a line with the OpenSSH version, in another - telnet does not connect at all - ..Failed to open a connection to this host, on port 22: Connection failed.
At the same time, in the windows services and applications snap-in, the service has the status “running”.
Restarting the service for a while solves the problem.
Below is the OpenSSH config and service log.
I will be grateful for answers.
Thank you.
