After v34-10 click on Fortnite to launch LS-0013 error keeps show up.

Summary

This issue started with update v34.10. Every time I try to launch Fortnite, I get the LS-0013 error. It’s becoming really frustrating.
First, I tried verifying the game files, but that didn’t work.
Then, I deleted the webcache_4430 folder, which allowed the game to launch once, but I had to delete it again every time I wanted to play.
I uninstalled and reinstalled Fortnite, but the LS-0013 error still persisted.
I hoped that update v34.20 would fix it, but it didn’t.
I then completely uninstalled the Epic Games Launcher, cleaned every Epic-related registry entry, and removed all Epic-related files from C:\Program Files, C:\Program Files (x86), C:\ProgramData, and User folders.
After reinstalling both the Epic Games Launcher and Fortnite, the issue still remains—LS-0013 keeps showing up.
At this point, it seems like an issue with the Epic Games Launcher or my Epic account, as I never had this problem before v34.10.
My map no longer appears in Discover, even after the latest update.
A discussion I was having in the Need Help? tab suddenly disappeared, which has never happened before—it usually stays.
There have also been numerous crashes on Xbox after v34.10.

Can someone please help?

LS-0013, I think thats an Easy Anticheat error, I read somewhere certain PC LED software can cause it or maybe a certain mouse driver

Thanks, I will take a look at it.

I found the cause of the LS-0013 error—it was related to the web browser settings. The first time I installed the Epic Games Launcher and Fortnite, I did it through Google Chrome. Later, I changed my default web browser to Microsoft Edge in the system settings for a dumb reason.:sleepy_face:

Even though I could log in to the Epic Games Launcher, UEFN, Unreal Engine 5.5.4, and all Epic Games sites like the Creator Portal without issues, my account was still being blocked under webcache_4430 because it was originally linked to Google Chrome. This caused various problems, including Fortnite not being recognized for login.

After switching my default browser back to Chrome in the PC settings, the LS-0013 issue was resolved.
