Level editor blackbox crash

Try validating the game files within Steam. If that doesn't help, try re-extracting the editors - perhaps something didn't copy correctly. If still nothing, try reinstalling Visual C++ Redistributable, I believe you can find it in the _CommonRedist folder.

When I validated the Steam files, it has said (362 files failed to validate and will be reacquired) Reinstalling the latest Visual C++ Redistributable didn't work either, also tried re-extracting the editors before.
