Сбой с EXC_BAD_ACCESS (SIGSEGV) в .NET 8 и Silk.NET Vulkan ⇐ C#

[Anonymous]

Я пишу код с помощью .NET 8 для macOS и библиотек Silk.NET Vulkan.
Я добавил библиотеки MoltenVK в выходную папку, но после добавления некоторого кода Vulkan произошел сбой.
Я посмотрел руководство на YouTube, чтобы изучить основы Vulkan и то, как он предназначен для использования. Я отладил код и он вылетел. Прочитав отчет, я подумал, что это потому, что я использовал скомпилированную бинарную библиотеку MoltenVK, а не «оригинальные» библиотеки от Nvidia или AMD для Linux/Windows.
Может кто-нибудь объяснить, прав ли я, и если да, то почему?
Вот отчет о сбое:
