iMovie keeps on crashing...

Hi everything was working fine until an hour ago when iMovie made a new update now I keeps on crashing. I have already removed the Events and Projects folders and emptied the trash as suggested by Apple on their iMovie page but it still doesn't want to load. I'm using version 10.15.7 MacOS Catalina

Any suggestions please.

thx Douglas

Try creating a new user account and opening iMovie in the new account. That's to rule out that there is a conflict in your present user account that is causing the problem.


You can also try opening iMovie in a new library. Hold down the Option key while opening iMovie and a box will appear where you can select a different library or create a new library.

Redownloading iMovie would be one thing to try. Sometimes that cures issues. Before doing it there are a few other things you can try.


You could try booting up in Safe Mode (see Finder menu for instructions) and, after everything loads, immediately shut down and reboot in normal mode. Then see if iMovie works properly.


Check to make sure that you have sufficient app free space on your drive for iMovie to function. Sometimes space can be used up without us being aware of it. Insufficient space can cause iMovie to crash.


Also, try the following procedures, as they are very easy to do and sometimes can cure crashing problems. It simply a matter of shutting down and rebooting while holding down certain keys.


Resetting the System Management Controller

If restarting the Mac doesn't cure it, try deleting preferences. Sometimes updates will cause preferences to become changed or corrupted. Deleting preferences will reset your preferences to the default ones. To delete preferences, open iMovie while holding down the Option and Command keys and select to delete preferences in the box that appears. iMovie will open in a new library. Reopen your old library to get back to your projects.  Deleting preferences is a safe procedure that will not cause data loss or disruption to your project.
