Have you tried checking to see if you have a weak internet connection?
Also, if you are urgently needing to work on a project, you can launch the UE4 project without needing to use the Epic Games launcher I believe. Go to the folder the project is saved in and double click on the (.UnrealProject) File.
Hope this helps!
I have a near perfect internet connection, and prior to about 3 days ago, I had no problems loading the launcher. I kid you not, I woke up one morning and the launcher didn’t work anymore. At this point its more annoying that there is no solutions out there and EpicGames hasn’t helped at all.
i have tried many things, watched some videos on youtube, made changes in the firewall and it did not solve the problem
I fixed this issue after watching this video! Video link
I hope this will fix it for you as well!
