Final Cut Pro hangs at 22% while sharing project on M1 MacBook

I have been working on a project for the last 3weeks. I am now ready to share the file. I have started the process and it hangs at 22%.

I have rebooted the MacBook with M1 processor, 64gb, 1.3tb free space. No other applications running.

I have reset preferences in Final Cut pro

i have cleared the library of unused files.

There are lots of resources for the app to use.

Is there an analysis that can be done to determine the video or audio clip that the app is hanging on?

I don’t want to lose all this work. Thanks for any help, or ideas to a solution.
