I just installed UE 5.7.1 and its crashing:

Fatal error: [File:D:\build++UE5\Sync\Engine\Source\Developer\DerivedDataCache\Private\DerivedDataBackends.cpp] [Line: 208]
Unable to use default cache graph ‘InstalledDerivedDataBackendGraph’ because there are no writable nodes available.Add -DDC-ForceMemoryCache to the command line to bypass this if you need access to the editor settings to fix the cache configuration.

Hey @Bruh97! Welcome to the forums!

Can you check that your username on windows does not have any accent marks on any of the letters? And then after that- and this seems to be the biggest cause of this- if you have any VPN active you need to disable it. Most of the places I find this issue that seems to be the common reported fix.

Hope that helps, let us know if you get it figured out, ok? :slight_smile:
