How do I import TestMeshProUGUI?

error CS0246: The type or namespace name 'TextMeshProUGUI' could not be found (are you missing a using directive or an assembly reference?)

I had this in my project, something very terrible happened, my Unity project wouldn't start up, I got it somehow fixed, I opened a new project, the first line of the error showed up, decided to start a new project and copy all the Assets in that new project, didn't fix it, I thoroughly uninstalled Unity and Unity Hub including restover files, I reinstalled Unity Hub, downloaded a new version of Unity, copied my files into that new project into that new installation of Unity and I still have that error.

I thought that TextMeshPro was once an asset in Asset Store that was bought by Unity and since then was included in (every?) new project of Unity, but now I can't seem to get it back to work. I uninstalled, scrubbed and reinstalled entirety of Unity and still no effect. How do I reimport the vanilla version of TextMeshPro?

 

I get the same error regarding 'TextMeshProUGUI'... sadly scouring these forums still hasn't provided me an answer, but I'll keep searching.


Wishing you success.
