I have exactly the same D3D12RHI out of memory error even on new Third Person View project. This error happens only when I go afk for something like 30 minutes. I have no idea how to fix it at all:
Here is a link to my log file in case someone can understand something from it and give an advice of how to fix it https://www.mediafire.com/file/gihz61ghcttlvps/ForRender_copy.txt/file
It happens only on Unreal Engine 5.5 right from the first version of 5.5 to the last one 5.5.4. I don’t have such issue on UE 5.4.
