Premiere Pro 'Not Responding' when using Team Projects

Hiya,

I keep getting the Not Responding notification when working on Team Projects. When this is the case Premiere will allow me to work on a project for a while, then it will crash. When I restart Premiere it will work for a shorter time and then crash. The length of time for which Premiere works then gets shorter and shorter until it gets to the point where a mere click on a newly opened project will crash it. My computer is brand new and has good specs. It's been working fine for the last 3 weeks until now. I thought the issue was with OneDrive as it was backing up to it and the drive was full. Then I diverted all the auto-saves/cache folders to my harddrive (which has loads of room) and it still kept crashing. I wondered if some files were still somehow backing up to OneDrive so I deleted my OneDrive and no change. I've tried resetting preferences and resetting workspace to saved layout. I'm not very tech savvy so wondering if there's something basic I've missed. It only seems to do this for Team Projects which I use all the time.

Please help, somebody!

Thanks,

Sophie
