Using Revit 2019, latest Rhino WIP and RhinoInside version, getting the following behavior consistently, tested on two machines.
Launching the rhino window first, then the grasshopper window causes Revit to crash without any additional error notice/ pop up. However, if I launch the grasshopper window first, followed by the rhino window, the program does not crash.
Please let me know if I can provide additional information about the crash/ build/ etc. Thanks!
