I am using Pro version 3.4.3., and I have several projects on the go at the moment. The main problem I'm having is that whenever I try to open another project, or just close the project I am using, ArcGIS Pro just crashes and I can only close the program in task manager. Also, when I am in a project the "backup in progress" message appears A LOT and I have to pause work while it processes. Overall, ArcGIS is also running quite slowly and making even simple tasks take a long time. There is nothing wrong with my PC setup and all other software I have is working fine, this problem is definitely within Arc itself. This problem is happening with all my projects, old and new.
I have repaired the software within Windows but this didn't help. Any advice would be appreciated.
