It happened before the upgrade too.
I finally figured out a workaround. I opened the project on another system and removed the bins one at a time (some recent footage had been giving me trouble, which is what gave me the idea). When I removed the three most recent shoots from the system, I could open the project fine. Mind you, this is not a corrupt media file that’s hanging up the project because I had taken all of the drives offline. This was a corrupt bin, I guess? Is that possible? For a bin to become corrupt? So weird….
