Our users started having trouble opening some large aprx files on ArcGIS Pro last week, and those files opened normally earlier in the month with no major changes. Some large aprx files for a project can open, but we're having a growing number of files across different projects that cannot open. Most of the time, these files would stay at the loading screen without opening even after a few hours (see attached image).
We've been troubleshooting for the past week and tried the following:
- Rebooting our virtual servers (Citrix) where our GIS files are located
- Updated latest patches for ArcGIS Pro 3.1.4 (what we're currently using with our Enterprise license)
- Clear/refresh caches
Despite our efforts, we're still having difficulty opening these files. However, we were able to open one of those aprx files by copying the entire project folder onto a different network drive, and then opening it on ArcGIS Pro 3.6 (the latest version) on our physical desktops.
