ArcGIS Pro 3.5 will open, then jams, cannot force quit

[GerryGabrisch]

One GIS user (one out of many) has an issue where Pro opens, the user can open a project (any project) and then Pro stalls.  The user cannot kill Pro using the Task Manager and the only solution is to restart the computer.

I have done a complete uninstallation, purging of the contents of  C:\Users\thisuser\AppData\Local\ESRI, and new installation of Pro.  

I can confirm that the users project are not jamming on my computer and seem to work without issue.  No other users have this issue.

Windows 11, ArcGIS Pro 3.5.  The computer meets the minimum specifications for running Pro.

Soft reset, complete reinstall and Tech Support would be the order assuming the computer has been tested to meet the minimum (at least) specs

Perform an ArcGIS pro Soft Reset

Perform a Clean Uninstall and Reinstall of ArcGIS Pro 

make sure that the registry changes/edits are made in the latter
