Strange artifacts everytime in the same place, packaged game UE5.7.4 please help

Hello i got this strange artifacts in the photo below, when i walk into an almost precise area of my world partition map, the issue starts suddently everytime in one single place/location and goes on for undefined time when i walk and look around, is like flickering fast based on view, but seems there is not a direction to stop it, the screen goes from normal view to this reduced view with the lines only on right and bottom borders, seems not a player camera problem, seems without a real cause, is like an interference of something, i checked all possible problems(collisions etc..), nothing in output log, i tryed on 3 PC’s with 3 different video cards happens only in one PC, i have other dozens areas similar but no problems, only there and only on one pc the one with RTX2060. Then, in some way, after some time or distance from when it starts it goes away, also if i restart the game, so it is sure somthing that clash, but i not see nothing strange in that place, i have only post process volume in that area and not coincide with the issue area, nothing more than some meshes, in editor no problems like the other 2 PC’s.Anyone got the same problem or can help?
Thank you in advance

Update, i discovered that when it starts flicker/lines, it continues also if i walk in before location where normally is not triggered, so the interference remains before and after that point.
