Packaged Project Crashes

When I launch my packaged project, it crashes with the following message:

214636-crashmessage.png

It’s a 100% Blueprint project and works inside the editor.

I updatet the engine to 4.17.2. Before I thought, it might be this bug: [Answerhub Question] (4.17 + 4.17.1 Packaged Game Crash on Launch - Platform & Builds - Epic Developer Community Forums)
, but this is said to be fixed now in 4.17.2.

Any help would be great!

Just solved the issue on my own.

Converting the project to a c++ Project by adding an empty c++ class, and the issue is gone.

Earlier I migrated some Blueprints (from a c++ Project) to this Blueprint only Project.

These Blueprints maybe had somewhere unimportant references to c++ assets, maybe there might have been some c++ asset that came into the Blueprint project.
According to this article it doesn’t need to be a problem, but somehow it’s logic and it caused the packaged game to crash on launch even if the standalone game in the engine worked without any issue.
