Grasshopper wont load Rhino 6 and 7

Hi I’m looking for help to troubleshooting a problem which has just started in the last week. I can start Rhino have 6 and 7 on my machine, but when I start grasshopper it goes through the loading bar the freezes on the grasshopper green logo and locks up. This happens on both Rhino 6 and Rhino 7 I’ve not added any new plugins for a few weeks and after the last one, it was working fine. Windows 10 machine.
Rhino 7 build 7.7.21160.05001 Grasshopper build 1.0.0007
if I run _GrasshopperDeveloperSettings if freezes with no action
if I run _GrasshopperLoadOneByOne and say no to all plugins I can get to a grasshopper canvas

Where can I find the logs to trouble shoot the plugins pls or what should I look at to find more info.

Thanks in advance


Further investigation has narrowed it down to ironbug.grasshopper.gha is causing the load to fail.

I will move this issue/bug to Ironbug plugin.
