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:
{85527100-19D0-45AF-9F09-DAB4E711C35E}
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!
