Error writing tile to file

Exact steps for others to reproduce the error

From the top of Blender select Edit -> Preferences
Navigate to the File Paths tab.
Change the directory of Temporary Files to a different folder folder.
Change the render engine to Cycles and increase the resolution or decrease the tile size so tiles are used.
Render the scene and after the first tile is complete you should receive the error Error writing tile to file.

Can not reproduce here on master (3f7014ecc9d5)

Hi Alaska, does this happen with both CPU, GPU?

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:

Open default blend file
Assign path for Temporary Files
Switch render engine to Cycles
Decrease tile size
Render as Image

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.
