macOS crash in debug mode - 0x103bbf324 dart::Assert::Fail

[filiph]

After letting my app run in the background for a few hours (in debug mode) and switching back to it on macOS, I experienced a crash. The app just suddenly closed, with the Flutter tool saying Lost connection to device. and, later, macOS generating a Problem Report ([application] quit unexpectedly).

Steps to Reproduce

This will be hard to impossible to reproduce but I do have the Problem Details and the System Configuration, so I thought I'd report it anyway.

Some things that seem salient from the Details that I'm copying here for SEO:

Thanks for the report @filiph
This seems similar to an already open issue #103268, so please check if underlying comments in it resonates with your use case that triggered the crash. If so, we can club this issue with the linked one for better tracking.

[mraleph]

I don't think it is the same issue as #103268, the assertions are different.

[filiph]

This could be a red herring but my app also (like #103268) listens to key events (it's a Flame game with mouse+keyboard input).

[darshankawar]

I'll label this issue based on the report and for team's attention.
