Workbench crashes when anaconda is on the PATH

[phargogh]

A student in the InVEST class was unable to launch the InVEST workbench on Windows, and the workbench logfile looked like this:

[17:57:56.399] [C:\Program Files\InVEST 3.14.2 Workbench\resources\app.asar\build\main\main.js] i' due to unhandled exception!

The specific PATH entries that were preventing InVEST from launching were:

• C:\Program Files\Anaconda\Scripts
• C:\Program Files\Anaconda\Library\bin
• C:\Program Files\Anaconda\condabin

When the student removed all three of these entries (I do not know if they tested each one individually), the workbench was able to launch.

A few other observations about the student's system:

• Windows 11
• The user's username had all ascii characters and no spaces, e.g. C:\Users\phargogh\
• There were no gdal-related environment variables defined
• There was a PYTHONPATH environment variable defined, but it appeared to refer to a chemistry workspace, and so was unlikely to have affected this situation.

The student had a username that was entirely ASCII character

#1610 is related since it'd be helpful to inspect the cause of the error without having to dig into the logs directory.

I tried reproducing this on a Windows VM and was not able to. I first installed Anaconda, which placed about 5 different paths on my user's PATH, then I installed and ran the Workbench. I did not get any import errors.
