Video footage blacked out when importing from iPhone XS to FCPX
When I import media form my iPhone XS into FCPX, sometimes - on rare occasions, but enough for it to cause me problems - the footage comes through black out. The audio is fine. Happens if I drag the clips in or I cmd + I them in.
I can see this is a problem a lot of people have said they have:

It never got resolved. I'm using Catalina with FCPX 10.4.8
This has only happened to me since upgrading, but could be a coincidence?
The footage doesn't work if I drag it into my timeline from the downloads folder, or if I put it into the library first. Also, even if I create a new project (same library) or even a new library the importing doesn't work. Still blacked out.
To note, this works for most clips from ym iPhone most of the time. Just occasionally this happens. The video is question plays fine (audio and visuals) on my MacBook Pro outside of FCPX, so it's an import issue.
Can you help? I made a 30 second YouTube video demonstrating the issue: https://youtu.be/AdsiacplcsU
