How to enable GPU for MCTemporaldenoise filter?

[Toothache]

Unfortunately, the encoding doesn't work when the newly added Temporal denoise is applied. It just crashes with the error "...AppData\Local\Temp\2 TDG.265 was not created!"

I merely enabled the denoiser, and did not change any of the default options.

Tell me how to enable detailed logging, and I'll send the logfile.
