All of sudden, not enough Vram

I have often used the poduct Glowing Beach by Polish, a gorgeous scene in its own rights. Until recently, I could load up to three figures on it, 8.1 male and/or female with hair, anatomical parts and swimming attire and run it in sun-sky render settings without any sort of additional tweaking. Now, it looks like whenever I try to load one of these figures in that scene, even after removing all the candles, the boat and the tent with table settings etc, iRay just gives me the double finger. When the render is kicked in, here is what comes up in the log:

I tried updating my nvidia driver. I tried updating to the latest beta. I restart Daz with every attempt. I clicked the "default settings" button in the render settings, trying to go back to what used to work. It still doesn't work. The only way I found to get the scene to work was to reduce its textures with scene optimizer but I didn't use to need that. And the characters I am trying to load there are the same I used to load in that same scene, countless times. What should I do? All advice welcome O_o
(Hardware wise: I am running a RTX 3060 on a Ryzen 3700X, with 64 G's of RAM. My OS is W11 Pro.)

"Until recently"... Is that the same as until W11?
As recently as five days ago :)
Do the "3 triangle objects with 59 M triangles" belong to the Glowing Beach, that has been working, or are they something new?
15 light sources with 46269 triangles, sounds a lot for (outdoor?) scene
I'm still on DS 4.15, so I don't know what the DS 4.20 log should look like... There are some strange things there...
One thing that could cause such change, is if the Iray compression settings were somehow changed, causing the textures use more VRAM
Just to clarify, about your W11 question: I moved to W11 a month ago and I did try that scene after that. It still worked.
I just tried to re-render the same scene without a character. I kept the render settings that came with the scene, only lowering the horizon to get a gradient of blue sky (otherwise it'd be very white). It renders just fine. If I run the character alone wihtout the scene, it works fine as well.
I tried loading the scene and applying different settings for the suns/sky. The same 15 light sources remain, the triangles too, no matter what. I really don't see what they are...
The texture compression threshold is still set between 512 and 1024. GPU is selected for both photoreal and interactive, canvasses are not ticked (I did play with those a few times in the last week on another scene but didn't leave them on after that). One thing I noticed is that the normals are huge on that product.
If you look at the scene with wiremesh preview, you can probably spot the item(s) with 59M triangles
I am going to try and hunt it down but I suspect the island itself. However, it's still strange that a scene which worked just fine with some people less than a month ago would suddenly fux up.
I don't know if it matters, but the scene renders fine in iray preview. Only in a final render does it go tits up.
Have you looked at your log (Help->Troubleshooting->View Log File)?
Sorry...
If you attach your log to your message, there may be things that have an effect (do not copy the log to the message area)
An idea came to mind... Maybe something was installed/updated/enabled 5 days ago that eats up VRAM, you could use the Task Manager or GPU-Z to see, how much VRAM is in use when DS is not running.
I will do both these things, catch the log and attach it in a post, and check thoroughly what could have been installed in the last week. Sorry I didn't reply within the hour, I was still fighting with it and something odd happened. I still can't, as I used to, load 2 or 3 characters in the scene, but I managed to load one G8.1F fully loaded with the default render settings provided with the scene. And that didn't work at all unti half an hour ago. The only noticeable thing I did other than this was to reboot and play 10 mn of farcry 6 to make sure that the vcard reacted normally for other things. It's late now here, eleven thirty in the evening, but tomorrow I will follow your advice and I'll post the logs in here for you to see.
Thank you for helping me PerttiA!

5 days ago, I noticed that at the start of the Daz Studio, the line "connecting to CMS..." is visible for a very long time. I don't know what the CMS talked to the Studio about for so long, but after that there were complaints about poor rendering of heavy scenes, which just recently were rendered well.
For example here: https://www.daz3d.com/forums/discussion/576631/public-build-iray-not-working
But now the "connecting to CMS..." is visible 1-2 seconds. So, what happened to the Daz Studio 5 days ago?
*EDIT*
I think I found my culprit. The render subd for this character (and I can't think of why!) was cranked up to 5. I never set them up so high myself, usually sticking with 2 or 3 at max. Now, I can render two figures and do that so much quicker. Whatever modification I made to the character during the week, it seems to have reset my subd. Are there precedents to this?
It's good that you found the cause of the rendering problem. I think you implicitly solved the "public-build-iray-not-working" topic as well. There was also mentioned an object with 186 M triangles in the log file. This is too high a number even for a powerful graphics card.
I read somewhere on the forums about turning a figure into a prop. Assuming that you can do this, body, outfit, hair and shells, will the resulting prop eat less resources at all?
As I see it, no.
The difference between a figure and a prop is the figure is rigged.
In order to reduce ressources, you have to reduce geometry (e.g subD level), number of textures or texture size.
If it is a dressed character, you can hide bones covered by clothing, then they won't load when rendering.
Also, if you have a large scenary, you can use Iray section planes to limit what is sent to the renderer.
I'll have to work on using iray section planes then.
