Crash when using Vulkan with Dreamcast Games (Flycast)

Is there an existing issue for this?

• This is a bug in RetroArch frontend
• I have searched the existing issues

Description

When setting the Video Output to Vulkan, it just crashes instantly, when using gl/glcore/others it works fine.

Expected behavior

No response

Steps to reproduce the bug

Go to Settings --> Video --> Output --> set to Vulkan
Start a Dreamcast Game using Flycast

Version/Commit

1.21.0

Bisect Results

No response

Present in the nightly version

I don't know

Platform & operating system

Linux amd64

Affected Cores

Flycast

Environment information

Using Linux with Wayland. Vulkan works in other applications fine and the Vulkan tools tell me, that i have working Vulkan Support. Other Cores worked fine with Vulkan so far too, but non of them use 3D Rendering

Reproduce the crash by launching a Dreamcast game with Vulkan on Linux/Wayland, then inspect the assertion at deps/glslang/glslang/SPIRV/GlslangToSpv.cpp:281. Trace the Flycast Vulkan path through core/rend/vulkan/vk_context_lr.cpp and core/rend/vulkan/vulkan_renderer.cpp; done means the game no longer aborts during Vulkan startup.
