[BUG] PC Crash with High View Distance after Update 39,00/39,10 - Cannot publish map

Summary

Since the recent UEFN update (version 39.00 or 39.10), my map crashes on PC when View Distance is set to High/Epic. Before this update, everything worked perfectly.

My island was working and published before update 39.00 Now I cannot publish updates because the UEFN update causes crashes that trigger the 1.14 rejection.

bro uefn is getting worse and worse .
i also have a problem where some props disappear when the game is launched , you see them get destroyed when you start the game for no reason , i reported this problem 3 days ago , and still not fixed , before the update everything was okey , now they messed up everything .
