Try the latest version to see if it works.

I fix a crash that could happen if you use live sync auto and quickly switch context.

Other than that ideally I’d more information on what was typically the last operation done in Nomad/Blender (deleting mesh, sculpting, dyntopo, etc)

3

I’ll test the new version and will update if there’s any issues that exist. And will try to record to steps to recreate them.

4

Actually don’t waste your time too much, I’m still fixing a bunch of crashes.
And many things are changing (adding hierarchy to app link, etc)
