On Windows 10. Latest helios despite the hash in path suggesting otherwise.

This specific sample is from BDNkq6u7y96Yx7sh.BDNkq6u7y96Yx7sh.BDNkq6u7y96Yx7sh.BDNkq6u7y96Yx7sh.VQT3KUN9BKLtQ8nA$VQT3KUN9BKLtQ8nA, however nearly every method errors with that stack trace, always complaining about u'\u200b' for this sample.

Seems to be related to try-catch of the class \u200b\u2004

Unfortunately my old windows laptop is in the closet and barely works, so this will be hard to test. I'd recommend just commenting out the print statement and see if that works.

That fixes it.
