Unity Namespaces aren't available

I wanted to continue coding where I left after sleeping, but suddenly as I open my Code in Visual Studio and tried to work on my code while having using UnityEngine.UI or using UnityEngine.EventSystems standing at the top, it just says that the type or namespace "UI" or "Eventsystems" doesn't exist in the namespace "UnityEngine". And I also can't use using TMPro. I don't know if thats all I can't use.

I've now just restarted my pc, reselected Visual Studio 2022 17.2.5 in Unitys external tools and uptaded Visual Studio and it sill doesn't work.

Maybe it's important to know that restarting my Unity project isn't working.

How to fix that and how to prevent it from happening again?

Open Unity and go to Window > Package Manager. In the Package Manager window, select In Project from the dropdown as shown below.
enter image description here

In the list of packages, find Visual Studio Editor and update it to the latest version.

Close all Visual Studio windows, go to Edit > Preferences > External Tools, and regenerate project files (In your case, the External Script Editor is Visual Studio).
enter image description here

Reopen any script in your project and the error should disappear.
