报错：Library\PackageCache\com.unity.package-manager-ui@1.9.11\Editor\Sources\UI\Common\PopupField.cs(8,36): error CS0246: The type or namespace name ‘BaseTextElement’ could not be found (are you missing a using directive or an assembly reference?)

Anyway, your error can be resolved by selecting Help -> Reset Packages to Default.
