How do I fix Lightroom Classic, that has just given me this message: 

Lightroom cannot start because it cannot create files in the temporary file location “/var/folders/3k/w4p5k0l52lj1f59qym9k3jx40000gr/T”? I had downloaded a card that I probably corrupted when I removed it from the computer without ejecting it. Now LRC won't open at all.

Find your catalog file on your hard disk and double-click on it. The default location on MacOS is /Users/[username]/Pictures/Lightroom/ (but of course it may not be in the default location)
