ShaderMaterial not working in CanvasItem and spamming infinite errors

[KoBeWi]

Godot version

09e12ba

System information

Windows 10 x64

Issue description

This happens when you assign new ShaderMaterial to a sprite:

It becomes invisible and spams hundreds of errors per second.

The errors are similar as in #62525, but the issue is recent and doesn't seem related.

Steps to reproduce

1. Add Sprite2D
2. Add ShaderMaterial

Clear your .godot/shader_cache/ folder and that should solve it.

The problem is that we don't do proper cache invalidation when breaking rendering changes happen.

Removing shader cache indeed fixed the issue.

EDIT:
Worth to note that there are 2 shader cache folders - in .godot directory and in user directory. You need to delete them both.

Thank you! Not finding the user shader_cache was keeping me on alpha 10.
