I was in the middle editing, took a break and came back to discover I can't access my iMovie. It's blank and when I try to open it I get “iMovie Library” is already in use by “me” on “my MacBook Pro”. Of course it's being used, I'm using it. What do I do?
Hi,
Try restarting your computer. Also, force quitting iMovie from Apple Logo/Force Quit.
If neither of the above cure it, try opening iMovie in a new library by holding down the Option key as you open. See if the new library is functional.
You can also try deleting 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.

Here are a couple of more things to try:
Go to your Movies folder in the Finder (Go/Home/Movies) and double click on the library's icon. Does iMovie open in that library?
You can try to access an earlier backed up iMovie library from the iMovie backups folder. To get to the iMovie Backups folder,
follow this file path from the Finder menu:
Go/Home/Library/Containers/com.apple.iMovieApp/Data/Library/Caches/iMovieBackups
When you get there you will see a list of previous backups of your iMovie library. Click on one dated just before your issue started. iMovie will open in that library. Navigate to your projects browser (where your projects are displayed as icons) and see if your projects are intact.

“iMovie Library” is already in use by “user” on “user’s MacBook Pro”.
