Thank you for that. I’ve packaged the project successfully and been able to launch it without any problems. After doing so, I compared my packaging log with the one you provided and the only difference seems to be the message about missing this file:
LogUObjectGlobals:Warning: Failed to find object ‘Object /Game/2DSideScrollerBP/2DSideScrollerOverview.2DSideScrollerOverview_C’
which is repeated multiple times, but there is no mention of this in my log. Another user I saw that had this issue reportedly fixed it by verifying his engine’s installation through the launcher. This could explain it since it’s not happening with my installation. Could you give that a try and see if it helps?
