Unreal 5.1.1: "TimecodeProvider Plugin" supported on Linux?

When I load a project on Ubuntu Linux which was created and developed in 5.1.1 on Windows, Blueprints which derive from UAudioCaptureTimecodeProvider cannot be edited without a warning that the editor may crash due to the parent class being NULL. The “TimecodeProvider Plugin” is indeed enabled in Edit → Plugins, so I’m wondering if this plugin (which is in beta) is simply not supported on Linux yet.

I sure would love to find a workaround, as I’d really prefer not to have to dual-boot to Windows. As a developer, I much prefer Linux. Any help would be appreciated. Thanks!
