BSD process name corresponding to current thread: WacomTouchDriver

My computer (MacBook Pro 15" Late 2013) has been randomly shutting down lately. It doesn't seem to matter whether I'm working, watching a show, or it's just sitting there. The error is always:

panic(cpu 4 caller 0xffffff80125cccdf): "thread_invoke: preemption_level -1, possible cause: unlocking an unlocked mutex or spinlock"@/BuildRoot/Library/Caches/com.apple.xbs/Sources/xnu/xnu-4903.271.2/osfmk/kern/sched_prim.c:2420

and this is always consistent too:

BSD process name corresponding to current thread: WacomTouchDriver

I've updated all my drivers and programs as best i can, but this is still happening. Does anyone have any advice on what I can do to try to fix this? I always send my error reports to Apple, but of course they never do anything.

Here's the full latest error report:
