gpu crash with Unreal Editor

Hi i need help figuring out why my gpu crash sometime, not all the time, when i launch the game, its a simple default map with nothing except a small platform. The GPU crash and i need to restart my computer so that i work again. I use a RX 7600 from couple hier ago with a recent R7 7800X3D

Edit : I made change thing like to dx11 and disabling nanite and lumen, but still persist
Edit2 : I found that it always happen after i looked at the sun, and if i cap fps at 60 it doesnt crash, need more help to know what make it crash
