Launcher crashes after Login

Development Getting Started & Setup

I’ve spent this afternoon researching, but none of the methods I found worked for me.

Suddenly (nothing new installed), after Login in in the Epic Games Launcher, it crashes. The error is the following (last line of debug log):

LogWindows:Error: === Critical error:
=== Assertion failed: VaultCacheDirectories.Num() > 0
[File:D:\BuildFarm\buildmachine_++depot+UE4-LauncherLive\Portal\Source\Layers\DataAccess\Private\CommunityPortalVaultCache.cpp

So, appearantly the VaultCache is causing problems? Alright, I cleared it. No change. Uninstalled already 2x as well.

Any Idea? I mean the error message shows that it must be the VaultCache… (Can upload whole log if requiered)

Thanks

Hi CosmosXXX,

Thanks for reporting the issue, if you could provide the full logs that would be great. Also seeing as its a crash any crash dump files that haven’t been been uploaded already would be very useful these would be in the same location as your log files if they haven’t been uploaded yet. Please make sure you are reporting the crashes using the crash reporter, if you can’t find a crash dump can you please get us your epic id that would have been shown in the window of the crash reporter before submitting it.

All Logs
Thanks very much for the response. I simply attached now all error logs I can get. (they’re all from just now; tried to start the launcher once more a sec ago.)

Hi CosmosXXX,

Thanks for getting us all of that information, from investigation it seems that you have installed the launcher inside of a folder called “Programme & Games”. Your folder name has highlighted a previously unknown issue with the launcher, and we will be fixing this in future updates.

In the mean time you need the launcher to not be inside of a folder which contains an “&”. You could try removing that & from the folder name and see if that fixes the issue. If you have always had the launcher installed here you may experience issues with your configuration information being out of date. These might manifest themselves as issues detecting existing projects and an invalid default installation location for apps such as Unreal Tournament.

You could edit these values in:
C:\Users\AppData\Local\EpicGamesLauncher\Saved\Config\Windows\Game.ini

It should be clear which ones if any point to what would now be an invalid file location.

Alternatively you can uninstall and re-install the launcher to a new location, however this may wipe any engine downloads and downloaded vault cache data you have.

Let me know if this fixes your issues.

Thanks, that was the simple fix. Thank you very much!
