Real-ESRGAN webm conversion not working

[AlbinoKiwi]

Tried to upscale a 1080p webm 4x using Real-ESRGAN. It splits the webm into frames, the threading and parallel frame options seem to work fine, but the upscaled frames folder is just not populating with the upscaled frames.

I can see the conhosts and each of the -vulkan.exes seemingly processing the frame, but it seems to not be writing out the upscaled frame. I've got an NVIDIA 3090 paired with a 11700k.

Multiple driver installs and restarts later it seems to be working as intended.
