Please provide any additional information below.
There were no other addons updated at the time Quartz was, so I didn't have any confliction speculation.

Same problem/same error is on my machine.

Right after install it seemed to work well, but after some time playing the bars froze (buffs only). Reloading relogging didn't fix it but showed this error which didn't go away after.

Edit: interesting to know is that I tried to change the buffbar text-color, but that didn't have an effect, it remained white. Might be related.
