Black video clips - FInal cut pro 11 problem

Hello, I have a serious problem with Final cut pro 11. After updating to the new version of Final Cut Pro 11 and updating the project library, my media (which is fine) appears black on the timeline, and relinking videos doesn’t work. Reinstalling Final Cut Pro 11 or changing the folder where the videos are located doesn’t help either. The video files are stored on a disk in their usual folder, and there has never been an issue before this update. This is a big problem because the only way to fix individual clips is to select them and choose "Transcode Media." While this restores the clip and makes it work on the timeline again, it creates unnecessarily large data files. How can I fix the project if this problem ( I am using MacBook Pro M1 Max and Sequoia 15.1 update)

Here is a picture:

Thank you for any help.
