Crash When Building GPU Lightmass (Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x0000000000000078)

So am currently working on a small game, and I had to switch from Lumen to RayTracing and use GPU lighting as building the light normally would give me some blocky effects.

I didn’t have any problems but as I progressed in building the map I would occasionally build the Light, as a consequence I would sometimes crash with the frequency increasing as I progressed, and now I crash every time I build the Light.

I have already tried resseting the Global Defaults on the NVIDIA Control Panel. And I’ve tried deleting the DefaultEngine.ini with some previous steps as its explained here.

The problem persists the same, and I just Crash when trying to build the Gpu Lightmass, not when opening the project or doing anything else.

I have a:

RTX 2080
Core i7 9700K
32GB or RAM

Finally this is the Complete Log I get:

Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x0000000000000078
