Crash when opening project in 4.6.1

I downloaded `godot-benchmarks`, opened Godot 4.6.1 and imported `project.godot` which immediately crashed on macOS 26.3. Next time opening Godot, the `godot-benchmarks` was already in the project tree but opening it again, without recovery mode, crashed it again.

Reproduce the crash by opening project.godot from godot-benchmarks in Godot 4.6.1 on macOS 26.3, using the supplied crash report as the baseline. Start at OS_MacOS::open_dynamic_library and GDExtensionManager::load_extensions in the stack trace, then determine what happens when the project is opened. Done means the project opens without crashing on the reported environment.
