Dart_PostCObject_DL failed after Hot Restart

[brianquinlan]

I was just hit by it. It never occurred since today and it occurs on Hot Restart, almost at every app launch.

Log

@delfme Could you confirm that this only happens with Hot Restart?

[brianquinlan]

I think that we will have to live with this until https://github.com/flutter/flutter/issues/75528 is fixed.
