Resolution Note (2022.1.X):
The shader happens to cause a crash in Microsoft DirectX shader compiler (FXC), which unfortunately is a black box to us. Fortunately it seems to happen only when #pragma enable_d3d11_debug_symbols is enabled in the shader.
For a workaround just remove or comment out this pragma line in the .shader file.
NOTE: It is not possible to disable pragmas using preprocessor conditionals. The shader in this bug report falsely assumes it would be possible.
