hi, can you create a new tpp template project and directly do packaging? see if it packages fine or same error comes? and also, location also matters like make sure, project or the destination exe file is not in a sub-sub folders location
Hey, I think this is a similar issue which i had few days ago, but after checking your objects list on the right of the screen, it could be related to your object’s name which are too long for unreal engine to compile. A list of the objects causing this error should be found in your logs.
lol ahemmm
