HELP!! Updated FCPX and my projects have red warning MISSING PLUGIN
I really need help, I recently updated to Monterey, and also updated FCPX, but now my projects are full of the warning; Missing Plugin. As I didn't know I needed to, as I haven't had a problem before, I have not got backups of my libraries.
I did have a back up of FCPX 10.5.1, but as the libraries have been updated, now they won't open.
I cannot lose all my work, what do I do?!
MacBook Pro 13″, macOS 12.0
