Hey quesques!
Thanks for all the info……so this occurs across multiple applications I see. Could you please see if the same results from searching Spotlight or even Finder?
Search for anything with Spotlight on Mac - Apple Support
If Spotlight isn’t working correctly you can follow the steps here:
Rebuild the Spotlight index on your Mac - Apple Support
If multiple apps are affected, you can drag/drop the entire volume of Macintosh HD (typically) into the window to then remove it.
You can tell when the indexing begins by pressing Command and the space bar, to pull up Spotlight search, type in any character without pressing Return and you will see a progress bar indicating that it’s indexing, this process can take a while, even a day or so to complete, depending.
Otherwise I think knowing if the same happens in another user account is one of the best isolation steps to try out, if needed, you can just create a temporary user account just for this:
Add a user or group on Mac - Apple Support
The resolution may depend on the results of those steps, let me know how it goes, glad to help out if I’m able to!
