Points not displying in grasshopper

I updated to the service release Rhino 7 SR3 2021-1-26 (7.3.21026.13001)
now, it seems that points selected or generated in either rhino or grasshopper are not displayed.
I can select them in rhino using “selpt” and they show as valid in the point component but do not display within the viewport. Nor do points generated from within grasshopper display show up.
any insight is most appreciated.


attached screenshot should show several points within rhino and several points generated within grasshopper as the vector startpoints.

updating my own question.
After updating the OS ( Windows 10, version 20H2) and the latest rhino update Rhino (7.4.21040.1300)
problem seems to be resolved.
