There is the message
[2025.04.20-09.29.14:592][234]LogValkyrie: <MemoryStats.PageSize>4096</MemoryStats.PageSize>
Thats 4GB!
like 32GB at least maybe 6400 64GB its Windows 11 needs massive virtual memory
There is no memory space to swap out programs, run the Editor, or Push/Rev Control. The Garbage collector is running all the time and finding nothing!
Currently Freed 361216bytes from 16 GC contexts
This is definitely wrong

Lol.
This is pretty weird. I never though this could be the problem. I will try it.
I tried @Jimbohalo10 fix Can't create C++ project ( or use C++ ) and sometimes when changing from window (or Fortnite) back to UEFN the PC totally black out. I can not do anything. The computer starts to put all fans to max power and all screens all black and I need to restart it.
I will back again to the older Memory configuration. This fix was far worse than the original problem.
Edit: After changing the memory configuration to the older one, the problem has come back
I just tried with 64k MB, the black outs dissapeared and the application hung probability decreased, but still is a big problem
just to add i had the same issue and changed my file size to 128gb i think and i dnt get it much anymore maybe the odd time if i leave it on for a hour or so and not do anything. You could increase the file size more if you have the space for it
