EXC_BAD_ACCESS KERN_INVALID_ADDRESS Style/notifyStyleLoadingStatusIfNeeded Crashes

Hi, I am getting this bug/error quite a lot (1% of app opens). It is an immediate crash, that happens in the first second (after Crashlytics).

The crash happens on iOS 18.6, 18.7 and iOS 26.1, oddly I cannot find any other versions.
All devices, new and old iPhones and iPads
We tried downgrading to 11.15.4, happens, also all versions up to 11.16.4!

The bug appeared after we upgraded to Swift 6! That could be a hint.

Thanks for any help
Tobias

No source file or test is named. Start with the EXC_BAD_ACCESS stack in Style/notifyStyleLoadingStatusIfNeeded and reproduce on the reported iOS versions with Swift 6 and the affected Mapbox Maps versions. Done means identifying a reproducible cause and verifying that the crash no longer occurs.
