RuntimeError: CUDA driver API error CUDA_ERROR_OUT_OF_MEMORY (code: 2, file:D:\a\1\Luxcore\src\luxrays\devices\cudadevice.cpp, line: 516): out of memory

You are simply running out of GPU ram while trying to render 124,565,410 triangles (!).

Hi im experimenting a lot of CUDA API "Crashes" with a very simple room scene...

124 millions of triangles doesn't sound exactly like a very simple room scene

Do you have some "out of control" subdivision, etc. ?
