Been wrestling with this issue for a while, narrowed it down to a mixin error that only occurs when Quark is installed.
I'm hoping this is a conflict I can resolve.

Unfortunately this IS the full log, it doesn't give me any sort of crash report whatsoever. When Quark is removed, it boots up without incident and I'm baffled as to why that is.

If you can reproduce this with a proper log then please open a new issue

Quark or zeta isn't even mentioned in that log, send a full log and preferably a crash log
