If you go to the Maps folder and then TheIslandSubMaps folder and all you see is Level files(no white blueprintgeneratedclass files) then the EpicLauncher is using the correct(fixed) content and binaries. You just need to be patient.
Everyone is so quick to force close the DevKit when it stops responding. You’ll know if the DevKit has crashed as it will either just close without warning, the popup appears or when you’re in the task manager the CPU and disk usage are at absolute 0 indicating that the process has completely stopped responding.
I just loaded a random PGD and it took several minutes, longer than normal to say the least, to fully load as if you remember the game went through about 7 major version changes since our last update… that is a lot of changes that the DevKit needs to process in comparison to everything it knew and had stored in its cache.
So, just be patient, open a PGD and walk away or go do something else on your PC for a period of time. If the process has completely stopped responding in Task Manager, then it is a proper issue.
How long it takes depends entirely on the various aspects of the machine you run it on.
