Bug Cannot access database - The project you are opening contains a locked Library/SourceAssetDB file.

I am a student who is new to learning Unity. A few weeks ago, the computers in the classroom where my project is stored were moved and replaced without my knowledge. After having moved my project onto a flash drive and moving it to my new computers, (Both were Mac computers running MacOS), I attempted to re-open my project, but I encounter the following error:

"Cannot access database - The project you are opening contains a locked Library/SourceAssetDB file. Make sure that there is no file lock or another process having this file open."

The SourceAssetDB file is marked as unlocked in file properties. I attempted to follow other solutions, such as deleting the Library and Temp folders, and deleting the SourceAssetDB file, but nothing has worked so far.

Because I am a student, I cannot efficiently employ solutions that require admin access.

Thank you.
