macOS runs fail with an `libc++abi: Pure virtual function called!` error

[Yarwin]

Our actions fail semi-randomly for macOS builds (both x86 and ARM) with:

libc++abi: Pure virtual function called!

I don't have a Mac myself, but this has reproducibly happened in a GitHub Actions run. Probably as a result of closing Godot (SIGTERM).

(first of all, sorry for all the confusion 😅)

What should we do about it?

Ignoring failures is worse than not running examples at all (it wastes resource on generating pointless noise), so it is not an option 🤔.

For now on I utilized retry.sh script and made sure the run indeed fails on failure after few retries. If it fails at least once I'll disable macOS runs and resort to compiling only.
