4.4-dev6 VisualShader: Error: Parameter "version" is null and then after a while crash

[SWCreeperKing]

Tested versions

• Reproducible in: v4.4.dev6.official [1f47e4c]

System information

Windows 11 - Godot 4.4-dev6 - Forward+ - dedicated NVidia RTX 2070 super

Issue description

the output console will be filled with

ERROR: Parameter "version" is null.
   at: version_is_valid (servers/rendering/renderer_rd/shader_rd.cpp:659)

when clicking the eye icon on certain nodes with certain inputs
it seems like it has to do with inv_view_matrix and the preview from the eye icons in the visual shader

Steps to reproduce

make a visual shader

connect [input: inv_view_matrix] and [input: vertex] into [TransformVectorMult: A x B]
connect the [TransformVectorMult AxB] into [Texture2D: SamplerPort: UV]
connect [Texture2D: SamplerPort: Color] into [Output: Albedo]

now whenever you click the eye icon on the output of either the [TransformVectorMult: A x B] or [Texture2D: SamplerPort: Color]
the output console will be filled with

ERROR: Parameter "version" is null.
   at: version_is_valid (servers/rendering/renderer_rd/shader_rd.cpp:659)

and then eventually crash

I'm able to reproduce the issue that spams the error in the output console, but it has not crashed (yet).

However, if I use the latest build from master dc5f1b7 it does not spam the error anymore, instead I have this error (spawned once) every time I click the eye icon of either the TransfomVectorMult or Texture2D node :

 ERROR: :12 - Unknown identifier in expression: 'n_out2p0'.
  ERROR: Shader compilation failed.

@AThousandShips Confirmed. On the version it was reported on it spams the error; on master it still shows up but only once each time the eye is clicked. I get an extra error in my sample project, but only on the Texture2D eye, not the Transform one:
