That would be great, but it depends on whether an application can programmatically determine that, which I doubt it can. It is one thing to try and access a file and get permission denied, it is another thing to determine it has or has not been awarded Full Disk Access. I am sure people would also feel frustrated if they were to get an erroneous "need full disk access" alert; or feel that there could be some malware, in case they received a real "need full disk access" alert...

This ^! OMG. I was pulling my hair out trying everything. FCP was acting so odd with this misleading Missing Plugin error, but this "Full Disk Access" change fixed all of it immediately, and my large project saved.

For the sake of others, it started with my project no longer playing audio (audio is separate files in my project), then a bit later audio waveforms started to disappear. I could sometimes re-drag the original audio file into the browser and it would start working again, for a bit then stop, other times I couldn't re-drag, no pattern that I could tell. I started clearing optimized files and other temp data (Peaks, Thumbnail) in the Library package, thinking maybe it was corrupted, that's when video disappeared and this Missing Plugin showed up for all my video files (thus the video I was seeing before was just optimized files which masked the broader issue). I could re-drag the video files in, and FCP would re-optimize them (I could even see and view in the Finder the optimized video files within the library file), but the Missing Plugin remained. Restarting FCP, clearing Setting/Preferences of FCP (cmd+opt when starting FCP), Relinking, Relinking in different locations, nothing was working. But this worked. FWIW, my FCP library and original media files are on a dedicated external SSD (APFS formatted).

OP Where did you find this nugget of information from? Anyway, thanks for posting it.

There are a number of applications that do that at first launch, ask permission to be granted for specific system settings. Remote for Mac is one, AlDente is another. Carbon Copy Cloner asks for disk permissions.

I agree. Since FCP relies on having Full Disk Access permissions, it should have a pop-up when it discovers it does not. Please send Apple your feedback via Final Cut Pro->Provide Final Cut Pro Feedback...  or Feedback - Final Cut Pro - Apple

Please show me the screenshot you took with shift+⌘3 and explain.

This "issue" applies to all applications on macOS now, not just FCP.
