Hey everyone-
When retrying the steps that originally reproduced this issue (Unreal Engine Issues and Bug Tracker (UE-46610)) again in 4.17.1 from the launcher, I was able to run the packaged version of the project without running into this error. Additionally, creating a project and enabling nativization (Inclusive and Exclusive) did not show this error when launching the packaged version. Please let me know if you have reproduction steps or a sample project that demonstrates this behavior.
