This is an error/warning message that I am getting while opening the Revit.
Hi @saniul_hoda
Thanks a lot for posting your question to the forums! Can you try the below.
As Repair/Reinstall is not available, uninstall Revit, then reinstall.
Note: If the reinstallation does not help, check if Mandatory User Profiles are used and if so use Reaming Profiles instead.
