Python script editor not loading

the PhythonScriptEditor does not open. Tried it in R7 and R8beta. No luck. Works fine in Rhino 6 though. Also, Grasshopper freezes Rhino 7 & 8 when trying to open it. On the feedback line of the Grasshopper pop-up window loading stops with ghPython. Any idea what I could do to fix this? Don’t want to jump back to 6 all the time I want to use grasshopper.
