Hi guys,
I just rented a new Macbook Pro for editing on vacation and got into the same problem that you are having.
my problem even tho is, that i caint create a new projekt anymore at all, because everytime I'll get this error.
what i have figured out is, that it ONLY happens for just created projects and ONLY for them that are created in a subfolder of a database, so if i want to create a new project that belongs in a folder structure, I'll have to create it right in the database and then drag and drop ist all the way there, were i want it. from then on I've never had a problem.
Hopefully this can help anyone of you and hopefully BlackMagicDesign will fix this within the next update (as they've done it in the past (props for that by the way))
Kind regards from germany, Jonathan J-)

Okay, so I did what i thaught was helping, and i was abled to save the project untill i renderd it. So i thaught, lets close this project and it came up with this *** error, so i thaught okay, my last save caint be that long ago, propably I'll only lose 5min. of work ore so, but as i closed the project, the project was gone
To save what you've done so far you can at least copy all that is in your timeline and paste it into a relying one.
now I have no ideas left and would highly recomend to have live save activated, to see error happening as soon as possible and maby see some connections that could explane this myth. good luck
