I got a libgit2 error -14. Some database file is locked, preventing me from opening my project.

I was working on a character animator project.
While trying to use the Automatic head movement based on audio feature.
The system froze and I had to Ctrl-Alt- Del to end task and restart the Application.
Upon trying to open the project. I got the error posted in the screen shot.
- Looks like some lock on a file, or something. Is there a way to fix it.
- I followed the path, listed in the error, to the master file in the head directory.
Can some dev, or support person tell me, if there is anything i need to be able to turn off, in the file, to get it to release the lock, so that the I can gain access to the project again thanks
