Revit 23 dynamo starting error message

It has something to do with Helix Add-in.

Helix is the library which is used to visualize the Dynamo geometry.

This error message is either because the CPU isn’t configured or because you’re missing a Revit / Windows update.

@mohamed.rashad4TVXU search the forum for ‘no background display’ and you’ll get a half dozen posts from myself and @Michael_Kirschner2 indicating how to fox the issue.
