Try build template in standalone game and have Fatal Error, in developer build have this
In editor work fine. In editor in separate window same error
Blueprint template work fine. Engine from Epic Launcher
The TopDown template has the same error. I am trying to package a newly created project without any changes. If I select “None” in the Animation Blueprint everything works fine.
BluePrints projects works fine. I use vs2022 and Rider (without rider nothing change)
Also getting this error on the C++ third person template. Just started a udemy class and they call for a quick test build, but they’re using the old third person template (they’re also in a beta version of UE5). I’m just in the intro phase of learning C++ (and coding in general) so I have no clue how to even start sorting through an error like this.
Adding the log from one of the crashes – scanning through, it’s not able to find some DLLs, but I’m not sure if that’s a factor.

A temporary solution (after all, there should not be errors in the start projects) clear the c ++ class and create a blueprint class where to assign the player. If the class is not cleaned from the code in it (not completely, only pawn assignment), then even without using this class below the game will still crash.
