Revit UI blinking and weird problems

In my case, Rhino.InsideRevit stability problems are getting out of hand. For a long time, it was working well. Strangely, it was more stable when Rhino was in the beta version.

After updating to Rhino 8.3 I can reproduce one scenario in which Revit 2022.1 and 2024.2 (on different computer) crashes. The same procedure for Revit 2023 is working fine.
Unfortunately, I installed Rhino 8.3, the new RiR daily build, and Ladybug Tools all at once and I’m not sure what the exact combination of factors is crashing Revit.

I reverted to the RiR 1.19.8739.18619 and the problem still exists.

How to reproduce the crash:

  1. Start Revit and Rhino.Inside
  2. Do not click on the Rhino icon, click on the Grasshopper icon instead.
  3. Wait a couple of seconds for the silent crash.

How to avoid it:
Before running the Grasshopper, click on the Rhino icon, then Grasshopper.

In short: I have different Revit versions on different computers and on both computers I can crash Revit with the described steps.

computer 1:
Reverting to the RiR 1.19.8739.18619 and uninstalling Pollination didn’t remove Ladybug Tools from the Grasshopper (probably because I used LB Versioner?) but apparently resolved the problem (Revit 2024).

computer 2:
Uninstalling Pollination and having the latest RiR (1.19.8746.29632) or 1.19.8734.22138 with Revit 2022.1 didn’t resolve the problem.


I’ve spent way too much time today on this but if you have some tricks to try I will try them, I really need all of these products to work together.
