Cycles CUDA error Launch failed cuCtxSynchronize results in Blender stuck in
Open, Needs TriagePublic

Description

Hey guys,
sry if I made any mistakes or any info you need is missing but I'm very new in this forum and need your help ... I've been googling and searching all over the place but couldn't find anything regarding my error.
I've a scene in Blender which should not be a big deal to render out through Cycles Render. But as soon as I start rendering (via Shift+Z or F12) it throws me the error:
CUDA error: Launch failed in cuCtxSynchronize(), line 1372
and after that it just gives me the error:
CUDA error at cuCtxCreate: Launch failed
I tried messing with my tile size, nothing worked. Changed the Path Tracing/ Branched Path Tracing settings...
But I noticed it renders just fine as soon as I use my CPU to render. Although that is extremely slow and not a real alternative to me ...
The Console Output looks like this:

I use a GeForce GTX 1080 Ti with 11 GB of VRAM so VRAM shouldn't be an issue. And I'm also not running any other VRAM heavy applications in the background ...

Any help is appreciated.

Have a great day!

Apparently it has to do with my smoke simulations ... I don't know what though ...
