Application crashes after unlocking the phone – "failed to attach to thread: Permission denied"

After upgrading my Flutter application from version 2.1 to 3.27, some errors appeared. I managed to resolve all null safety-related issues, but one critical error remains.

Issue

When I lock and then unlock the smartphone while the app is running, the application crashes, and I see the following messages in the terminal:

I/mx.fleetmonito(30053): Thread[6,tid=30064,WaitingInMainSignalCatcherLoop,Thread*=0xb4000071103b4be0,peer=0x131426a8,"Signal Catcher"]: reacting to signal 3
