ArcGIS Pro 3.4.3 keeps crashing when closing a project or opening another project

[ScarletMaguire]

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.

Hi, thanks for the advice. Please excuse the ignorant question, does a soft reset wipe any important data (e.g. layers, custom toolboxes) from my projects?

[DanPatterson]

It doesn't do anything to the projects since they aren't being touched.  Besides "renaming" something means that it will be untouched and a new requirement (eg registry name) will be created

The problem seems to have been solved! Thanks for the advice.

Is your project on your C: drive or a network drive?  Do you have any custom toolboxes with models or python scripts?

Hi, my projects are on C: drive, definitely not on a network drive! And I do have one custom toolbox with one script in it but nothing major.
