Hi,you need to read your UE5 Crash Files,when you created new DDC you also created new registry key.
To remove your error you need to open “regedit” and go to "currentuser/software/epicgames/ and find local or global data cache and delete that registry key dont touch the deafult registry key.
There is no point to reinstall UE5 when registry keys stays on your PC.
