Disable Add-ins:
Sometimes, third-party add-ins can conflict with Outlook, causing errors. Disable all add-ins and restart Outlook to see if the problem persists. If the error disappears, enable add-ins one by one to identify the problematic one. Consider updating or reinstalling the conflicting add-in or seeking support from the add-in provider.
