Hi - we are going to need more information from you. The Pen display mode works fine here on Rhino 7.
When you start a new file from a factory-default template, create a simple box, and then put the viewport in the Pen display mode - does that work?
Please run the Rhino SystemInfo command and copy-paste the result here.
