We are seeing an issue that has come up since 7/20 release that appears to be caused by an update to Rhino.Inside. Rolling back to 6.18 release has allowed us to remove the rhino.inside Revit components that were causing the issues (specifically Query level see second image) and use the script again in the newer versions.
Thanks, To be clear. You couldn’t open the old definition due to a GH crash, but reverting to a 0.6 version (released in May) enabled you to open the definition and update the offending components.
This is fixed on the next release.
The version that we had on our servers that people were able to back install shows: 0.8.7845.20898.
