Finally I can fix it,
Just DONWLOAD the installation package from the official Epic Games website and install it in the same directory as when you first installed Epic Games, after that open the control panel → Uninstall a program → select EpicGameLauncher-> repair
both my devices run smoothly to download several games (Dakar Desert Rally & Rise Of The Tomb Raider)
Previously, when downloading games, it always crashed in the first 1-2 GB
Had the exact same error today after opening up my PC to troubleshoot some things after two days of Internet absence and got the same error a couple of times, it seems to have fixed itself and I’m not sure if I myself fixed it but here’s sorta what I did.
I rebooted at least one time, it crashed a few times but just as I was about to uninstall the App somehow went through, I logged back in and checked the updates and selected “Update and restart”. Error did not popped up again, and after second reboot, still running smoothly. It seems to be having some fluke errors recently, and my theory is due to how the Launcher reacts to the new Nvidia driver version, I’ve received an “Unsupported GPU” error just the day I installed it.
It’s kinda annoying honestly because if this is due to an update that needs to be installed, then how can we update our stuff if it crashes?
Ok so tried this
If anyone else gets here, I couldn’t get any repair or reinstall to work properly until I removed the EpicGamesLauncher folder from my AppData\Local directory. ie: delete C:\Users\yourUsernameHere\AppData\Local\EpicGamesLauncher
