Description

Hello,

I’m encountering a crash in my production app within the first 5 seconds of launch, with the following error message:
realm::Exception::what() const EXC_BAD_ACCESS (KERN_PROTECTION_FAILURE)

I’m unable to reproduce this issue during testing, but it occurs consistently in the production app.

I’m currently using RealmSwift v10.48.1.

Could you please help me understand the potential cause of this crash?
Additionally, has this issue been addressed in the latest release?

Thank you!
