Can you let me know why does we have errors in diagnostic monitor, steps to create are as follows:

--> Start ArcGIS Pro with /enablediagnostics 

--> Open project without template

--> Add map

and once the map is loaded then we see the errors in diagnostics monitor :

Missing class or assembly name: esri_mapping_edgeSnappingButton

Missing class or assembly name: esri_mapping_intersectionSnappingButton

Missing class or assembly name: esri_mapping_tangentSnappingButton

Missing class or assembly name: esri_mapping_snapChipToggleButton

etc [Attached screenshot]

Update: I ran "Can I run this" for my version of ArcGIS Pro and saw that I did not have the required 20 GB of free disk space (not RAM or GPU). I was currently at 185 out of the 200 GB assigned to my virtual machine. I cleaned out the Download and TEMP folders, which got it down to 170 GB (!). I'm not sure what all is getting saved by Pro in those TEMP folders, but clearing the cache in Pro does not clean them out. Once I deleted all the data in the TEMP folder, I was able to render the layout, save and move on. We'll see if the issue comes back if the storage space creeps back up, or if it's something else being created in TEMP (C:\Users\{username}\AppData\Local\Temp).
