uefn constantly freezing

Hey! For the last 3 weeks my unreal editor has frozen every single day multiple times. Nothing else freezes just the editor and then I have to close it from task manager. This is very unusual and makes working a lot harder. Almost every single time I hit push changes it freezes completely. Any tips you guys could offer on this subject, I have seen lot of people with same problem but no answers on their questions.

Hi Riot,

I moved this post from the ‘Unreal Engine’ section to the UEFN section.

I wonder what the specs of your PC are. I also wonder about your internet connection. (As someone with an abysmal upload speed might have problems when ‘pushing changes’?)

The only way I can think of to gain insight as to why you’re getting freezes is to take note of the last thing written to the log file before the freeze.

You’ll find this file at C:\Users\YOURUSERNAME\AppData\Local\UnrealEditorFortnite\Saved\Logs

I have a 4070ti and UEFN has been running amazing until the past 3 weeks. My internet connection is good as well, and I have seen lot of people who have been complaining about the same issue.

I will definitely check out the log file thanks for the tip!

This is the last thing in the log, do you know how to proceed?

Thanks for that.

I’m not sure what to make of the log other than there may be a problem with a Module.

The first troubleshooting step would be to ‘Verify’ your Fortnite and UEFN files. (Accessible by clicking the 3 dots next to them in Launcher and ‘Manage’)

If that doesn’t work, a list of steps to reproduce the freezing in a new, blank project would be helpful.

I verified both files a week ago that didn’t help either. Should I try deleting the whole epic game launcher with the games and then download them again?

I’d try to determine if your freezing is project-specific or not first.

I doubt reinstalling the launcher would solve anything. But so long as bandwidth is free deleting and reinstalling FN/UEFN is an easy thing to try. (Although, I don’t specifically recommend it, I like to think ‘Verify’ would be a robust repair)

It used to freeze on me many times per day, now its more occasional, but still sometimes more than once in the same day.

I’ve gotten very used to making sure anything I invoke in UEFN is completed before I touch anything else in UEFN (otherwise there seems to be a much higher chance of a freeze up).

Maybe it’s a race condition between threads or something similar.

Every project freezes the same, I can push changes max 2 times and the third time it freezes sometimes it freezes right when I open the project. I can try to verify the files again, but hopefully I can find a fix to this because the last 3 weeks UEFN has been freezing non stop and that’s pretty weird given the fact that since the launch of UEFN it has been working amazing on my computer with no freezing or anything like it before.
