Error loading Pollination in Rhino 7.38 – TypeLoadException for ActivityTraceId from DiagnosticSource.dll

Hi, I’m running Rhino 7 (version 7.38.24338.17001, 2024-12-03) and just installed Pollination (PollinationGHInstaller-1.57.5). When I try to use the plugin, I keep getting this error:

Priority: CategoryIcon
{
Could not load type ‘System.Diagnostics.ActivityTraceId’ from assembly ‘System.Diagnostics.DiagnosticSource, Version=4.0.1.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51’.
TypeLoadException
}

Also, the Pollination tab and components do not show up at all in the Grasshopper interface.

Here’s what I’ve tried so far:

  • Reinstalled both Rhino and Pollination a few times
  • Removed old Ladybug and Honeybee plugins

But the problem just won’t go away. I noticed some people had this issue back in 2023, and it still seems to be happening now.
Is there any current fix or workaround for this? Would really appreciate any suggestions!

Thanks a lot!
