Reproduced with: Unity 2017.3.0b6, 2017.3.1p2
Not reproducible with: 2017.2.1p4, 2017.3.0a1
Fixed in: 2017.4.1f1
Wasn't able to test where exactly it regressed since Unity fails to build the project. The first version that reproduces the issue is 2017.3.0b6
Device: iPhone 7+ iOS 11.3, iPhone 8 iOS 11.0, iPhone SE iOS 9.3

I confirm this bug. Apps with Vuforia keep crashing on license check via WebRequest. It doesn't happen right away, but after ANY network issue whatsoever (Airplane mode not required), it keeps crashing every time you try to run the app. Downgrade to 2017.2 resolved the issue for me.
