After further review, I have figured out the issue. Although the package was successful without error or warnings for the problem, and the log didn’t list this anywhere as a reason for crashing; the problem ended up being an open level blueprint. As I mentioned, this project came from a PC project first, so I thought that the blueprints would work fine for mobile as well. The one that did NOT work for mobile as well is the autoscalabilty. It makes sense as all ios should work the same. Removing this level BP fixed the crash after splash screen. This can be marked as resolved.
