Hi Summit,
I found a recommendation from https://windowsreport.com . I will try it and see whether the problem will goes away.
Thanks!

Solution 1: Deleting Registry Keys
It is recommended that you should save a copy of your registry values before trying this making any changes. The solution will only work if you are logged in as administrator or have enabled administrative.
Navigate to your search box and type ‘regedit’.
A list of search results will be displayed and you can click on regedit to open it.
Move your mouse towards ‘HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Ole’section and delete the following keys: DefaultAccessPermission, DefaultLaunch, PermissionMachineAccessRestriction,
MachineLaunchRestriction
Finally, you can save the changes by restarting your PC.
The default permissions will be written for the system if you delete the above mentioned four keys from your registry. Hence those apps that require access to the DCOM Server will eventually get access as
a result.
