Slow Context Menu after Update to 12.29.1 Beta

Earlier today, I updated to Dopus 12.29.1 Beta. Since then, even after rebooting, my right click context menus in Dopus are very slow (up to a minute). File Explorer shows them instantly.
Any Ideas on where I could look to diagnose and fix this?

Would it be possible to make a Process Monitor log of what happens during a slow right-click?

The right context slow issue occurred on my OneDriver folders and files.
We followed your diagnostic procedures outlined here:

Crash, exit or high CPU when right-clicking certain files

In my case, the issue was with CLSID related to iCloud slowing context menu for folders and files in OneDrive. This is the CLSID:


Per your instructions in the aforementioned procedure, we added this CLSID to Opus Preferences Ignore_Context_menus.

We restarted Opus and this resolved the slow context menu issue.

Thanks again for a great product and for your superior customer support!

The ProcMon log could still be useful for working out why it became slow after the beta. (Assuming it wasn't coincidence with an iCloud update as well.)
