Rhino 8 crashing if I click on Tools|Options... after opening Grasshopper

Has happened two out of four times - can’t establish what might be difference between crash and not, Imm afraid.

And I don’t get the Submit Crash Dump screen. I will submit latest crash dump via the website.

Rhino 8.6.24079.11001, 2024-03-19

Maybe use GrasshopperLoadOneByOne, and then Options maybe narrow it down to a likely cause.

Just crashed on closing the startup examples panel in grasshopper. I’ll branch a new thread for that one and link the new crash dump to that.

I’d previously run a grasshopper script from Daniel Piker which warned ShapeDiver 1.16 (which I’ve never used) was wanted. I took the option to load it, and there seemed to be some muddle between whether 1.16 and 1.17 was installed, so I uninstalled it and restarted Rhino. That may, or may not, be relevant. As may be the fact that I had earlier installed the latest SRC.

It may be the ghpython module. A couple of gh startups without loading that and the crash didn’t happen. But it was intermittent so that’s an indication, not definitive. Conversely, with all the standard McNeel modules loaded and none of the third party ones, I did get a crash, so we can rule out the third party plugins.

In the meantime I’ve had a crash after gh opened and reached the point where it appeared ready for user input, without any user input having happened (except perhaps a mouse movement).

I’m going to reboot and see if Rhino is more stable after.

No more stable after a reboot.

I note that when I click on Tools|Options…, the cursor changes to a tail-less arrowhead (as it does while Grasshopper is loading). If it immediately reverts to a normal arrow with a tail, Rhino doesn’t crash. If it stays tail-less for a second or more Rhino will crash.

Consistently crashes if I load the ghpython module, doesn’t if I don’t. I reverted to previous SRC (14 Mar) and that has same issue.

When the ghpython module loads, does it run anything extra?

Eureka moment! Back when I was trying to load Shapediver for DP’s script, it said I needed to change the NET runtime from NETCore to NETFramework. Although I uninstalled Shapediver, I didn’t set the runtime back to NETCore. I’ve done this and the crashes stop.

I’ll leave it to McNeel to say whether failing under NETFramework is a bug.

Hi Scott, please see crossed post (marked Solution).

@jeremy5 I looked into this and can not replicate the crash. I think this might have been a conflict on dlls that handle Json loading. I’ll watch for submitted crash reports that might be related and will reopen the ticket.
