In My case the error was
Runner[567:39453] [VERBOSE-2:FlutterDarwinContextMetalImpeller.mm(37)] Using the Impeller rendering backend.
* thread #1, queue = 'com.apple.main-thread', stop reason = EXC_BAD_ACCESS (code=1, address=0x0)
frame #0: 0x0000000000000000
error: memory read failed for 0x0
In the Xcode It was showing error in NWPathMonitor().
The Problem was with connectivity_plus Flutter package.
Temporary Solution
Remove the connectivity_plus Flutter package, it will work fine.
or
You can upgrade the package. Else you can find the alternate package.
