macOS crash in debug mode - 0x105dadbf4 dart::Assert::Fail

This issue has been tracked since 2023-03-17.

This is similar to #119841 but doesn't look like the exact same crash, looking at the stack trace.

When debugging my Flutter app on MacOS and doing a lot of hot reloading, at some point the app just crashes with a "Report Problem" window.

Steps to Reproduce

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

I can also provide access to the current code so people can give the reproduction a try. The trick seems to be to just keep the game running and keep making Hot-Reload changes. I have crashed the game several times now in this way.

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

Gah! I closed the window before getting the whole crash report. I'll add one the next time this happens.
