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 @Styami

You will need to create a shortcut to UE5.3 Right Click Executable Create shortcut

in the short cut proprties add the text to the launch line

“-DDC-ForceMemoryCache”

which turns off the derived cache which is sitting in

C:\Users\”AccountNameOwner”\AppData\Local\UnrealEngine\5.7\DerivedDataCache

If you want to you can delete the 5.7\DerivedDataCache directory and run Verify from The Epic Games Launcher download section which will create a new clean version, but using the switch is the preferred method
