Zotero 5.0.35, available now via Help -> "Check for Updates…", includes the workaround mentioned above, so syncing with Box should work again. (If you installed the beta, you can switch back to the release version.)
Box should still fix the invalid behavior for their other users, but this should now be resolved in Zotero.
The error did not repeat this time. So, odd. But, good news. Also, Box has responded and they are working on the problem on their end. Thanks for the quick work, Dan!

Error during syncing.
To clarify, Zotero on Windows 10 worked after the update. Zotero updated on MacOS High Sierra 10.13.3 returned that error.
