Short description of error

I made a simple scene with smoke simulation (MANTAFLOW). After I baked the simulation, and checked in render view under cycles engine it worked well. After I tired to render a simple 1920x1080 image (with 32 render samples render volume 0.075, step size:1024.) the objects rendered well, but the smoke did not. I shift to CPU rendering (CPU type: i7-9750h 6 cores 12 threads) it works well, but under OpenCl again fail. Under EEVEE engine it rendered well.

How can I solve the problem, or it will be fixed in the future?

Thanks
Exact steps for others to reproduce the error

Could you please upload simpler file that could be baked and tested ideally in few seconds?

At the moment maybe a solved the problem. I checked the "Vector" pass in the original blend file, and while this was checked, the cycles does not work, only eevee. I made a short, animation without checking the vector pass, and it is work well.

Sorry for the late comment, I solved it just a few mintes earlier than your comment. Of course I will make a small bake asap.

No activity for more than a week.

Will close for now, but feel free to comment again if issues persist, we can always reopen then (make sure to include the smaller example file in that case, also, if this turns out to be an issue with the Vector pass specifically, please also note that in the report description...)
