[Clang] Internal compiler error when compiling a project with C++20 modules

Hello, when compiling my project with clang 22.1.3, I get the following error:

Start by running the provided clang-cl command with ScenePresets-5a9b01.cppm and ScenePresets-5a9b01.sh, then inspect the crash at DefaultScene in ScenePresets.cpp. Use the stack dump and preprocessed source to isolate the C++20 modules failure. Done means clang-cl no longer raises an internal compiler error for this reproducer.
