flutter – App crashes on iOS (Xcode) when trying to relaunch: gives me errors on debug mode and release mode

Relaunching my Flutter app on iOS (Xcode) sometimes gives me errors aka it crashes. It is very random. Note that the app does not relaunch at all in debug mode, so always fails after initial installation. In release mode, it occasionally relaunches the app. Note that sandbox mode is not enabled (don’t know if I have to do that or not) and I can provide any info you would like.

To reproduce:

1. Launch app via Xcode (always succeeds)
2. Close the app on springboard (screen) of iPhone
3. Try to relaunch the app
4. Loads splashscreen for 1 second and then terminates.

Here is the error log I managed to get:

domain: BSServiceConnectionErrorDomain; code: 3 ("OperationFailed"); "XPC error received on message reply handler">.

    NSUnderlyingError = <NSError: 0x2801a5e30; domain: 
BSServiceConnectionErrorDomain; code: 3 ("OperationFailed"); "XPC error received on message reply handler">;

I do not know what is causing the actual problem. I also see some other things:

Any chance someone knows what the actual error is here? Never seen this before and as the app crashes at reload, I can”t go live like this.

Note that here I found the sane issue, but sadly no solution:
