Answer 1

Yesterday I faced the same problem. In my case, the server was outside the domain. A search on technet led to a solution: in the absence of a domain, licenses "per user" do not work. Only "per device". We changed licenses, changed settings, the error disappeared.

Look at the task scheduler, there may be some rules that reset the license.
