Compiling Shaders MRQ "Failed to compile Material /Engine/Transient.Footage"

I’m getting a persistent “Compiling Shaders” during the MRQ output.

Pinned it down to this recurring compiling error. This is new since 5.4.4.

Hey. Did you fix it? I’m having the same issue and it’s definitely related to substrate.
