environment disappearing when i move close to it

this is the city sample project from the ue5 marketplace, when i open it the city and all the other things disappear when i move close to it and reappear when i move far,

the near clip plane is at 0.1 and i have tried other option too, by default it was at 10 and when i changed to 0.1 it still shows the exact same results,

i did restart the project, redownload the entire project from marketplace, still shows the same results

any idea what settings could be wrong, or any other problems you think could be happening
