HI Andreas,
can you please check a couple of things:
- The Operations Manager Event Logs
What do you see there, can you please check the entries and post the relevant events here? This way we could check them out and try to give some more useful advices.
- The SCOM Setups Logs
Can you please check the OpsMgrPatchWizard.log located under %LocalAppData%\SCOM\Logs ?
Can you post some of the last related log entries from the UR4 Install?
Do you see error in there?
- Last, but not least, please post a small feedback item on the SCOM feedback site. It just might be that you have hit a know isssue and the System Center PG could help you out:
Feedback System Center Operations Manager
https://feedback.azure.com/d365community/forum/2a49c9ee-4436-ec11-b6e6-00224824730c
Let's see what we can find out.
Of course, if you want your SCOM functioning again, you coozuld uninstall the Update as described here:
