Summary

Every time I want Calculate my Memory it stops at a random percentage and then It just keeps loading but nothing happens.
The Private Versions are sometimes shown but without the memory calculation so I cant upload it. Also my FOV gets bugged and I cant move inside of Fortnite while doing the calculation.

What are your system specs?

Unreal can be very CPU intensive. When swarm is running, it cooks my 32 Thread/ 16 core CPU at 100% usage per core.

Do you have anything animating in the scene? Or scripts running… maybe shaders compiling in the background?

No well I dont know my exact specs but that cant be the reason. I have more then enough good specs and everything ran fine before. Nothing is loading too long or lagging or whatever.

I can even start the game with UEFN while the memory is calculating and while being completely stuck.
But nothing is working

! FIX !

In my Project the Problem was the Proximity FUnction in the Settings. I had the distance set to the maximum. Putting it down fixed it for me
