DAZ stopped rendering all of the sudden

Greetings!
I know this issue may be familiar, but I have checked dozens of posts and threads and I have found no solution.
I have been using DAZ for months with no issue, even today: I have been doing renders perfectly for hours, until, all of the sudden, as I attempted to render another preview on the viewport, it stopped rendering. Now it does not render anything at all anymore; be it on the viewport, or a full render, it just stops immediately. I don't know why, I haven't changed anything or any setting or anything at all... and it just stopped working just like that, even on an empty scene with a single G8 figure with no lightning or anything. It just straight out does not even start using the GPU.
I have all the drivers up to date, it was working until a few hours ago...

It's runing out of memory on the card. It looks as if you haev high SubD levels set, though the system does seem to be lowering those to more manageable values, and your memory is also being eateen by the OptiX code used to emulate the RTX features.
Your graphic card ran out of memory and because CPU fall back is disabled it wont render.
But how/why is this happening? Some hours ago I was rendering huge scenes in very high resolutions filled with stuff with no issue, and now, it runs out of memory trying to render a single Genesis 8 figure? I don't understand... I have tried to restart DAZ, the computer... but nothing works... I have never had this issue in all these months... and I haven't touched or changed anything!
What is the SubD on that character?
Oh, now it works!
I was running some tests while restarting over and over looking for the issue... I believe an asset could be corrupt and breaking the program... is that possible?
Whenever I try to render anything including that asset, I get this error, and I keep getting it even if I delete it or change scene...
But if I restart, delete that asset and render or render pretty much any scene that does not include said asset, it works properly, as always... could all of this be caused by a faulty asset?
Once memory has run out in a session you do usually need to restart Daz Studio to free it.
I see... I still have this issue randomly, but it slves itself when I restart, as you say... It's just weird that, of all the time I've been using DAZ, only now it has started happening... I guess my issues today have come from faulty assets + A LOT of usage... so I will try to delete the faulty assets and, if this ever happens again, restart, and if it works, I'm happy hahah
Thank you all for your replies and help!
I have to ask again what does "Purge Memory.dsa" actually do?
Frees up some memory DS controls - e.g. the Undo stack, as I recall. The rendering issue is with Iray, or possibly the driver, not something DS has any control over.
