[Major] UEFN Won't Launch after newest patch still- Stuck on "90% Logging In" running for over 10 hours

I SOLVED IT! Using a Clean Boot of my PC I figured out actually that a software on my computer was blocking UEFN for some odd reason. If anyone else ever has this issue take a look at this website and you should be able to fix it!
