At our company we're using the embedded ServiceSDK for iOS (version 238.0.0) https://developer.salesforce.com/docs/atlas.en-us.service_sdk_ios.meta/service_sdk_ios/servicesdk_ios_dev_guide.htm

After the release of iOS 15 we have seen a lot of crashes in the Xcode Organizer for iOS 15 similar to the one in the stack trace below. After investigating we tend to think this is happening during the new iOS 15 prewarm.

Documentation from Apple: https://developer.apple.com/documentation/uikit/app_and_environment/responding_to_the_launch_of_your_app/about_the_app_launch_sequence#3894431

If anyone has an idea of what could be done to fix this I'd very much like to hear about it.
