Toolshed cache KeyError crashes startup from app icon

[nmforino@…]

Hello,

The program has been working without a hitch for some time, but now crashes
immediately after startup. To my knowledge I haven't changed made any
changes to the program itself that would cause a problem. A
uninstall/reinstall of the stable 0.8 build hasn't fixed the issue, and I'm
currently running MacOS 10.13.6 on my system. Any help would be appreciated.

Best,
Nick

Hi Nick,

Can you try running ChimeraX from the Unix command line and see if that provides any more info? In case you are unfamiliar with it, here are the steps:

1) Open Terminal.app in /Applications/Utilities
2) Type "cd " (note the space) and then drag and drop the ChimeraX app from a Finder window onto the terminal window, then hit Return
3) Type "Contents/MacOS/ChimeraX" and hit Return; ChimeraX will (try to) start

Let me know of any output you get in the Terminal window after launching ChimeraX

Hi everyone,

Thanks for the speedy and helpful reply. The aforementioned code
successfully launched the program, albeit a few errors got thrown in the
terminal, here they are:

Thanks again for the help, I'll get in touch if I notice any more problems
now that the program is working through this method.

Toolshed now catches KeyErrors when loading available bundles from cache and just ignores those entries.
