Tunny has been working fine until recently. I was running an optimization and terminated it early. Usually this isn’t a problem, but when I tried to reopen it the UI never appeared. I get the while border around grasshopper preventing me from interacting with nodes, but the Tunny UI doesn’t show up. I’ve tried restarting Rhino, restarting my PC, and uninstalling and reinstalling.
Are you using Rhino8 and Tunny v1 beta4?
Here is a list of possible causes.
1
There are several versions of Tunny v1 beta4.
Please make sure you are using the right version for your Rhino.
If you changed to NETFramework with the SetDotNetRuntime command in Rhino8 or Rhino7, use net48 Tunny; for Rhino8, use net7 Tunny.

It is possible that the log file is simply taking a long time to load. Please move the existing log file to another location or rename it and check the operation with the new log file.
It was in fact an error in the log file. I had gone to delete the latest trial from the log and missed the first line. I imagine it was getting stuck trying to load a log file that had no/insufficient content/information.
