-empty project gives no error
-tried deleting those folders, no good either
i guess ill have to try to re-install… but makes me excessively lazy, since packaging for android gives so much trouble too (nothing to do with this error, this error is for Windoes packaging)
i am pretty sure it must be some Blueprint corrupted. Is there any way to know which one is it in Visual Studio???
thank you very much for all those advices, ill try later to do the rest
