I tried the whole day to package my game. I seem to solved a lot of errors, but I still can´t package my game.
I hope somebody get an idea why or can help me.
I´m really happy about every answer and idea!
Thanks for your reply.
I also found out that my Subsystem for Steam is maybe broken. I couldnt compile a complete new project after I activated SubsystemSteam under plugins. I download the whole engine again and try to package then. I hope this helps.
