Cant launch

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.

Hi @Draco_Time
Let’s see if it works, other people had this problem
Maybe this one can help you

Unreal 5.4 crash/will not start "DerivedDataCache"

hi @PolyGons67 You will need to delete the file C:\Program Files\Epic Games\UE_5.4\Engine\DerivedDataCache Compressed.ddp This is corrupted and should be rebuilt on restart If this does not use the “Verify” function to repair from the Epic Launcher See the 5.4 Installer post 5.4 preview - Development / Getting Started & Setup - Epic Developer Community Forums (unrealengine.com)

Turning off my VPN solved the issue for me

We should not be forced to turn off VPN for the engine to open by default from the Epic Games Launcher. That’s kinda BS

Edit: And also doesn’t work!
