Unity does not support texture properties whose default value is a multisampled texture. Please remove the default attribute, and ensure that you always define a texture for that property.

Please, Can you elaborate what means "other than not declaring a default" in the resolution note?
I'm struggling on how to remove this error when calling Shader.WarmupAllShaders();.

Resolution Note (fix version 2023.3.0b1):
Unity was not properly detecting the case where a default texture property might be a multisampled texture (it is not technically supported by the syntax, so there is not a direct way to handle it in the shader other than not declaring a default).
