Daz Renders Failing - 'No device specified or usable'

Escribano

I did several quick test renders for a scene I was working on this afternoon, and then, suddenly, Daz was no longer able to render. The log suggests that the GPU is not available, although the diagnostic tool I have running is not showing any issues with the GPU. I tried restarting Daz, and then restarted the PC; still unable to render.

I have attached three files: the full log, a section of the log that includes my last successful render and the first failure (Render Error - Illegal Memory Access), and a section of the log that includes my last render attempt (Render Error - No Device), which was simply a cylinder primitive in an empty scene.

I am running Daz 4.21.0.5 Pro Edition (64 bit).

My CPU is Intel Core i5 10600K with 32 GB ram

My GPU is NVIDIA GeForce RTX 3090 with 24 GB memory

I am running trhe NVIDIA Studio driver version 528.49

I would appreciate any assistance in resolving this issue that any kind souls can provide :)
