Short description of error
If you change the temporary directory in preferences and try to render a Cycles scene with tiles, you will receive an error once the first tile is complete.

Can not reproduce here on master (

)Hi Alaska, does this happen with both CPU, GPU?
System Information
I can reproduce it on my CPU, and GPU (both CUDA and OptiX).
I have done some further investigation and found that more steps are required to reproduce this issue. I have updated my report to contain the extra information.
Thanks, I can reproduce now. Only happens when I assign a path for
Temporary files
.I am not sure if Factory preferences are responsible for this error to appear (it will just clear the given path)
To reproduce error, I did:
Temporary Files

The problem is that we initialize the temporary path for cycles only on add-on init, and if it changes the directory does not exist anymore.
The easy fix would be to just update the temp path on every render, but that's not correct if there are multiple renders running at the same time, so needs something a bit smarter.
Marking a few bugs as high priority with the aim of fixing them for 3.1.
