In our case, the issue was caused by the software BackupAssist. Uninstalling the software and re-installing version 12.0.4r1 resolved the issue.

BackupAssist Classic v12.0.4r1
Released August 28th, 2023
Urgent fix release
Urgent: Avoid “black screen” and other Remote Desktop/Team Viewer connection issues after reboots on installations that have applied Windows update KB5028166 on Windows 11 and KB5028171 on Windows Server 2022.
The root cause is a change in the OS that causes some services to fail to start when driver operations are unexpectedly handled as failures (eg. in CryptoSafeGuard Shield, various Anti-Malware drivers, etc).
You just made my day!
Thanks for this information, both servers have Backup Assist. I have tested on our internal lab server which also had the issue described. I installed version 12.05 over the top of the existing 12.03 and the issue is now resolved. I am able to RDP and have also put Screen Connect back on the system and both work flawlessly. No crashed display driver, no black screen, no problem 43 in device manager. I had forgotten this was even on the test server because it did not show in the add/remove programs (was installed under local administrator account when server was built and then was joined to domain, after this it no longer shows in start menu or add/remove), apparently it installs only for current user with no option to change.
Going to tackle client's server later this week but this looks like your solution is the fix for our situation as well.
Again, thank you, your sharing of information is invaluable.
