Flashing display and random crashes (Solved)

{UPDATE} I uninstalled my graphic driver and clean installed the NVIDIA studio driver. Now it has stopped crashing and flashing. Is it possible that the errors produced by the sword glitch corrupted the graphics driver? I wasn't having this issue prior to the update. Solved now and getting much smoother gameplay. I found the tip about using the studio driver when studying the best options for NVIDIA with Unreal Engine 5.0 [Resolved ISSUE] Since the update I have had flashing video and occasional hard crashes. The crash log ends with ntdll and after checking it indicated it was a possible launcher issue(I'm on Epic) I am reloading the launcher and the game and will post any change
