Mesh invalidated excessively during buildWSGeometry

DS 4.24.0.3 failed to even attempt to render my scene and this is the error in the log [: Mesh invalidated excessively during buildWSGeometry]. DS 2025 also failed to render the same scene but I haven't checked that log yet. All I could find online was a reference to this bug being fixed in DS 4.11. Any ideas?

Yes, get back to 4.23.
Rolling back to 4.23 didn't fix it. Any other suggestions?
So, does anyone know what this message means? I have a scene that's refusing to render in Studio 6, and I don't have any idea why. This is the only rendertime error in the log, and then it just stops.
The messages above that are ... odd. It implies that it stopped even trying to render before it did anything.

If the issue was that the video card didn't have any memory left, why didn't it throw to CPU? It's set to do that in hardware.
Other weird thing: that image started to render the first time, but it turned out that I hadn't turned Dome and Scene on in Environment. I did that -- nothing else -- and the scene failed without anything more than what you see above.
Yes, I think that's right... your 5080 ran out of VRAM ~ So you had Allow CPU Fallback checked in hardware tab ?
Suggest you install GPU-Z to monitor VRAM usage and give it more test... If there were still enough VRAM availabe but DS failed to render, that might be bugs. From quite a few posts that I've read, latest DS 6.x still doesn't work really well in terms of rendering ~~
