Steps to Reproduce

Launch Fortnite on PC.
Join any Creative or UEFN island.

Island Code

N/A (Occurs across multiple Creative islands)

Additional Notes

The issue is difficult to reproduce consistently but occurs frequently.
It only happens on PC.
The crash usually occurs while switching from one Creative session to another.
After the crash, the island may remain connected to the previous session, preventing immediate re-entry and slowing workflow.
This has been happening repeatedly and is affecting development productivity.

hi @CJ4301

Another dev in UK had a similar problem. He allocated a 250GB virtual Memory pagefile.sys on a spare SDD internal NVRAM. The fastest he could find then he added a 250000 (250GB) as in the Thread below, with size of latest UEFN at least 64GB is needed, when you swap between private island all the activity is happening on you PC. Both versions have to be in Virtual memory as you change screens.

IMHO there are no PC inside the $10K range that could support 250GB and justify the cost to an FNC dev, so using the pagefile.sys is a low cost.

in the thread replace 64000 with 250000
