It really is a strange bug … have you tried copying the whole project folder to another driver? As said, it was the only thing I did: moved project folder off SSD to RAID – nothing else changed, within 3min got Premiere working as it should by just moving the project folder (containing footage, project file …).

But what both of projects have in common: they are placed on a SSD.
I also tried before moving to the RAID editing off the internal SSD, was the same. Don’t have any knowledge if SSD’s are being treated different than normal hard drives by an NLE.

Hi!

I had the very same problem appearing 2 weeks ago while I rented out my 2016 MBP to a production I shot for. I was sure I had edited on the latest update of Premiere Pro without any problem. But the beachball came up for every click in the timeline! The editor of the production crew was going nuts! It was awful to know you had had an up and running system before, didn’t change anything and to start up the system and get presented with an unusable NLE!
Tried to clean and uninstall, tried older versions of Premiere – nothing. Today I was archiving the project and copied it from the external SSD connected via USB-C to my G-Drive RAID. Opened it up – everything fine!!! No problem anymore. Did a reformat of the SSD (previously ExFAT formatted to Mac OS Extended (journaled)), copied the project back and voilà – NO BEACHBALL anymore!!!
Maybe some of you can check and try different hard disks and make sure you’re using Mac OS Extended (journaled) as your file system.

best
