Question TMP Hidden InternalErrorShader after some unfortunate manipulations

EDIT : Issue solved, I was missing the "Import TMP Essential Resources"

Original issue
I'm was in the process of cleaning my git repo and unfortunately things went a bit wrong and I can't revert. In the process i accidentally put back an old text mesh submodule and it now appear that a lots of TMP based assets shaders are broken.

How could I diagnosis this? I bet there might be some shader ids that are all wrong, I could do a search/replace in VSC.

I tried to clear shader cache in the Graphics tab of the project but it didn't help. Actually I even tried to create new text mesh items (UI) but they have the same issue.

Thank you very much.

Exemple :


In view :

 

I found this line in the SDF Shader : m_Shader: {fileID: 4800000, guid: 68e6db2ebdc24f95958faec2be5558d6, type: 3}
And this one in the Sprite : m_Shader: {fileID: 4800000, guid: cf81c85f95fe47e1a27f6ae460cf182c, type: 3}

Could it be that shaders were lost somewhere ?
