Hi, thanks for the report. We need a sample file to test an investigate the problem locally.
Please remove objects, shaders, textures, etc. if you can not share the complete file.

Do you use daily-builds frequently? If so, had you ever rendered this file in previous 3.6 builds? (just want to verify whether its a recent regression)

Hi, not daily, I download every 2 days or something, will investigate what causes the error, if I removed the objects or textures it might work fine, will see what I can do and update you. thanks

So after testing, the issue is caused by these assets, once they are activated in My scene for render, the render produces these errors, I couldn't upload textures the file becomes 180 MB and it says too large for uploading, the textures where in 4K when I lowered them to 2K they produce the same issue even after lowering the resolution, keeping in mind that the scene renders perfectly in 3.4.1 with these assets even in 4K it's only in 3.5 and 3.6, let me know if there is a debug report or something I could produce, Thank you

so I'm using persistent data, each time I get this error or any other one and I try to hide objects in scene or disable or change anything, it keeps showing the error when I re-render, as if it doesn't update or free what's left in ram, even if I empty the scene completely, once i hit render it instantly shows the error.
I have to close blender and reopen it, then hide what causes the issue, and render, if I got the error there is no way around except closing blender and reopening it again. even if persistent data is turned off, when I re-render it shows failed to create cuda context

Hi, can you reshare the file with low resolution textures?
Without textures error is not appearing here.
This report could be same as #105442

it won't appear, it appears in the full scene, this is just the assets that cause the issue when they are activated in the scene. unfortunately I couldn't upload even the lowered textures says too large for upload, let me know if there is another option. hank you

Will close the ticket as we do not have enough information to redo it locally. We also have identical report so I think its safe to close this.
Thanks again for the report :)

so here's something I noticed, the full scene can render up to 1K when activating the Simplify option in render and adjusting the render res. to 1K, once I adjust it to 2k it gives the error, and it uses more vram then 3.4.1, once it reaches the vram limit it gives the error i think, 3.4.1 did't reach the vram limit and renders fine in 4K, in Vram stats in blender 3.5 it gives the error when reaching 7.5GB, 3.4.1 it reaches 7.6GB then I see the Memory increases then renders, just something I noticed don't if that could help or not.

There's not enough information to go on here. The Test.blend is set to Eevee, has no camera, is not using persistent data, so it's not clear what else is missing there to reproduce this.

To make the file smaller, image textures could be set to Generated with a simple grid instead of actual textures.
