Anyone deal with checkerboard lighting at random?

Hello, I’m not sure if this is the proper method to respond to this issue but attempting to resolve the issue did not work as intended. I created a post process volume, set it to unbound, and set the max and min brightness of auto exposure to zero. It only made the level blindly white and covered the artifacts. I will include a video at the bottom of this comment like last time.

My apologies for not responded sooner, work kept me away for some time.
