Weapon becomes blurry for no exact reason during a match

Sometimes during matches, weapons start becoming blurry for no reason at all. It’s not the suppression effect, it’s not due to explosions, frag grenades, flash or stun grenades.

This starts happening randomly and it comes and goes multiple times in a match.

It happens pretty often to me on PS5 Pro so it’s not like it’s rare. I have all motion blur to 0 and I have also turned vignette and chromatic aberration off.
