New macbook. iMovie freezes during editing.

I have a macbook 2020. When I edit iMovie I get a spinning circle and it freezes. This usually happens while I am deleting a video. The only way to get out of it is to restart the computer. Are there any fixes for this?

MacBook Pro 13″, macOS 11.1

I have no idea what is causing it but whenever iMovie (or any other editing app) starts behaving strangely for no obvious reason, the first thing you should do is delete the preferences.


 Hold down the  Cmd and Option keys as you launch  iMovie and this window will appear.



Click “Delete Preferences” and  iMovie will open in the default (as-new) mode with no projects etc. on the interface. 


You will have to navigate to any project you were working on and reopen it.  Your project libraries by default are stored in your Movies folder unless you have specified somewhere different.
