Rhino inside Revit issues

Met issues when clicked the rhino button in revit


Win 10 64
revit 2019
rhino 7.1.20299

potential problem core: GH plugin fennec

clicked the rhino button then these appeared
hit “close” then appeared the second pic
again then just revit left

Could you please give some advice? @scottd

It is this plugin: https://www.food4rhino.com/app/fennec

Does it load properly if you start Rhino by itself?
I would then remove Fennec, by deleting the Fennec folder" and see if it Rhino runs properly in Revit?
