Compilers doesn't recognize Unity.UI references

Hi,

I have since yesterday a really troubling mistake with compilers (VS and VS code) : they does'nt recognize references like UnityEngine.UI, EventSystems and TMPro. (CS0234 and CS0236) I have the same mistake on all my projects and tried to resolve it by all the potential solutions founded on the web. I use the latest version of Unity, compilers and packages. Can you help me to resolve this mistake please ?

Is Unity throwing the error or just VS / VS Code?
Have you imported the UI package from the package manager? Which version?
Have you imported the T$$anonymous$$Pro package from the package manager? Which version?
Can you provide your manifest.json in the Packages folder of your project?

Launch in Unity works perfectly, without any error. This is specific to the compilers.

I use Unity UI v 1.0.0 and T$$anonymous$$Pro 3.0.1 and there's my manifest.json :

   "dependencies": {
     "com.unity.collab-proxy": "1.3.9",

Can you:

Go into Edit > Preferences > External Tools
Ensure Visual Studio / VS Code is your external editor
Regenerate the project files using the button in the External Tools window

Close your project
Delete the Library (& Temp) folder(s), next to your Assets folder
Open Unity again

Uninstall & reinstall the packages again

I did (many times since yesterday) all you did, remove these packages : Unity UI, T$$anonymous$$Pro, VS and VS code for Unity.

I also deleted my library and temp files but the mistake doesn't seems to be about my project : every project have the same issue in compilers (include all new projects I have created for testing).

I reset all packages to default, nothing...

Finally I tried to remove all the versions of Unity and reinstall the last one, that didn't do anything...
