Basemaps won't load

[EliBD]

After recently updating ArcGIS Pro to 3.4.3, now the ESRI basemaps won't load at all. I can select them from Map>Layer>Basemap, but then I am left with a gray background. This is true for all of my maps in Pro. Basemaps still work in AGOL. What do you think the problem is?

Hey @EliBD 

Is this consistent with others in your organization? I'm currently in the process of updating my ArcPro to 3.4.3, but over a VPN, so when that finally finished I'll give this a shot too!
