Out of video memory crash when opening a certain level

“out of video memory trying to allocate a rendering resource. Make sure your video card has the minimum required memory, try lowering resolution and/or closing other applications that are running.”

So i am upgrading an older project to 4.26… was able to open the level. build lighting… then it crashed at the 100% of build lighting when importing all the lightmaps in. Since then i cant open the level… i am faced with that out of video memory crash…

I have an rtx 3090… so it makes no sense… even incrased paging file to 150 GB… nothing helps… What is going on ?

Seems like it opens if i put all settings to low, but then it crashes with the same error message if i ever try to build reflection captures of the level. It can actually build the lighting fine up to 100% but then gives me the error if it reaches the reflection capture building part… Can anyone help me???
