This is exactly like several other bug reports (#17798, #17799, #17921, #18218) in that they are all on Windows and the error occurs immediately after identical kvfinder commands are executed multiple times in a row. Weird. I need to check if on Windows there is some way to execute the command multiple consecutive times without meaning to.

There is also #18044, which gets the error without multiple executions, and after other actions are performed.

[Tom Goddard]

The error is definitely trying to access a closed model. But the Log does not show the user closing any model. Does KVFinder open and close models as you select lines? I think if KVFinder is closing models that is the key to debugging this.

[Eric Pettersen]

It doesn't normally close any, but if you run multiple ones then the later ones will close the previous cavity models. Nonetheless, running multiple commands on the Mac (kvfinder #1; kvfinder #1; kvfinder #1) works fine.

[Eric Pettersen]

Weird. On Mac, running multiple kvfinder commands successively works fine. On Windows, I get the error in this report. I still can't find any easy accidental way on Windows to get multiple back-to-back kvfinder commands to happen.

[Eric Pettersen]

Had to resort to patching the symptoms of the problem.
