UEFN keeps working, then acts weird and crashes, lags, failing login, and is unusable every few days

Summary

UEFN keeps working, then acts weird and crashes, lags, and is unusable every few days, I have tried to clear cache using %temp%, local, and more, and using DDU to clear shader cache, updating my drivers card, restarting my computer, and it still doesn’t work. Just note this is NOT a slow computer problem (I mentioned it worked fine a few days ago, i even tried to lower down scalability, and its not something in my background either.). I have also tried reverifying the game files, reinstalling, and it never works and it goes back to being normal to being unusable EVERY few days.

Even if this were to be manually fixable, it shouldn’t have to be like this so try to fix it. Still provide a way to fix manually for now.
