Hello Oliver,
It is possible that the issue is caused by too many services running on the server. You may need to review the services running on the server and disable any unnecessary ones.
Based on the error message you provided, it seems that the server shutdown is related to a licensing issue. The error message indicates that the server was shut down due to the License Compliance Service. I recommend reviewing our licensing documentation: https://www.microsoft.com/licensing/docs/view/Windows-Server
Note: For licensing inquiries, we recommend consulting with certified Microsoft licensing specialists or your vendor. Licenses constitute legal agreements between you and Microsoft. As tech support, our expertise lies in addressing technical issues, and we can offer only fundamental information.
Best regards,
Hania Lian
