Flickering squares on Chapter 3...I feel like I've tried almost everything

I've played through this so far but it is becoming very draining and even starts to give me a headache. These squares flicker, mainly in areas where textures reflect sunlight. If I am in a cave, everything looks perfect where no sunlight enters, and other Chapters look perfect as well.

I've tried:

DDUing the current GPU (3070) driver
DDUing to the previous driver
Tweaking all types of settings in game (open to trying any suggestions)
Starting the game with and without Vortex graphical mods
Verifying the files in Steam
Uninstalling and reinstalling the game

I've done my best to try to find someone else having this issue and I cannot seem to find any examples of this specifically. Any ideas on how I might be able to fix this? It's really stripping enjoyment out of this Chapter that seems to have a lot going on, which is a bummer.
