FrontBoardServices - [FBSSceneParameters initWithSpecification:]: Crash using CarPlay

In an app which support CarPlay (pre iOS 14, using MPPlayableContentManager and MPNowPlayingInfoCenter) I'm getting crash when I touch the app on the head unit. Based on the searches I made similar issue happened earlier but I didn't find any solution for that.

Similar issue to the one I am having: Why Does CarPlay Crash In Real Car?

Based on searches I made users found it also annoying that the were not able to use CarPlay apps for days.

Is there any fix or workaround for this?

Could it be that you added both entitlements to your .entitlements file? We had the issue that we received both entitlements (com.apple.developer.carplay-audio and com.apple.developer.playable-content) and added them both even though we haven't implemented the new CarPlay yet (using the CarPlay framework and SceneDelegates and stuff). In that case, the app crashes on iOS 14+.
