First window will not open map, have to open two to use ArcGIS Pro

[MeganWilson_wwu]

I have been running into an issue when opening ArcGIS Pro for the past few months and have found no solution. Every time I open a map (doesn't matter what it is) it will remain on the "Loading Map..." screen until I force quit the program. As a work around, I have opened a second window of Pro and have had no issues with being able to access and edit maps from there. I have tried to uninstall and reinstall ArcGIS Pro as well as having kept the software up-to-date, but nothing has worked thus far. Any insight is greatly appreciated!

The normal pathway before contacting tech support would be....

How To: Perform an ArcGIS pro Soft Reset

How To: Perform a Clean Uninstall and Reinstall of ArcGIS Pro  with the original at

Performing a clean uninstall of ArcGIS Pro | Esri Australia Technical Blog

If that doesn't work, then Tech Support is your best option.

On top of the resolutions Dan pointed out, you could clear your cache as well.

Project --> Options --> Display --> Clear Cache now

I was able to find a solution here: https://community.esri.com/t5/arcgis-pro-questions/arcgis-pro-opening-new-map-forever/m-p/1230227#M6... from Robert_LeClair.  Thank you for the help!

In addition to Dan's recommendations, a few other items to consider are:

1.  Are you using a docking station for your computer?  It's possible that it's working with an external graphics card docked in the system.  Remove the external graphics card from the equation and use the inbuilt graphics card in your PC.
2.  Are the prerequisite MS drivers current/installed?  One support case that showed similar issues had outdated drivers.  Updating them to the recommended drivers as referenced here fixed the issue.
3.  Run the program - "can your computer run ArcGIS Pro 3.3, 3.4 and 3.5?"  Sometimes it's a hardware issue.
4.  Sometimes disabling the integrated graphics card (the Intel one) via Device Manager -> Display Adapters fixes the issue as well.
