I tried the KB but didn't work.
I found this and it fixed my event viewer mmc error
- Open File Explorer on the device.
- Navigate to the following path: C:\ProgramData\Microsoft\Event Viewer\Views
- Backup the content of the folder. The next step deletes the custom views and you may want the backup to restore the views when Microsoft fixes the issues.
- Delete all View_X.xml files in the folder (it starts with View_0.xml and increments the number by 1 for each file).
- Start the Event Viewer after deleting the files.
