Thanks for your posting on Q&A.

Have you tried the tip to delete the wsus file under %appdata%\Microsoft\MMC and check whether it is helpful?
I would like sharing the screenshot in my lab below. Note that the path depend on the logon local user. According to my screenshot, the logon user is Administrator:

Please try to delete and reopen the WSUS console.

In the past, a lot of users feedback the issue occurred when they run the Server Cleanup Wizard. Also I would like to share the PowerShell script to cleanup the database. Here are several useful links for you：

https://learn.microsoft.com/en-us/troubleshoot/mem/configmgr/wsus-maintenance-guide

Also we could review the Event Viewer to get more error information.
Here is a reference screenshot for you:

Hope the above will be helpful.

Best regards,
