I cleanly reinstalled UE5 prview 1, now its even worse after 10-20 seconds it chrashes in the default open world map and/or empty map. Also for the first time UE5 EA has crashed on me, as if UE5 prview 1, has affected the other version. Both crashed in blank projects.
I subbmited a BUG Report.
100% sure it is an Engine Problem!
