After some editing in the attributetable, nothing fancy, just some text update, I get this error once or twice a day.

after that, attribute table displays columns but no records
I use arcgis pro 2.5.1, on a virtualized windows 10 machine having 4 cores and 16GB of which about 5 is still free
When I close arcgis pro, restart and re-open the project all is ok ...
Anyone else seen this?
