    It seems you're encountering an issue where the installed packages are not displayed in the Package Manager window. This issue has been observed when following a specific set of steps outlined below:

    1. Create a new project.
    2. Install any new package.
    3. Close the project.
    4. Create a new project.
    5. Open the Package Manager. The installed package from step 2 will be marked as installed, but not displayed.

    This issue has been reproduced with Package Manager UI version 2.1.0 preview 1, but it's not reproducible with Package Manager UI version 2.0.1.

    To address this issue, you may want to consider the following steps:

    1. Check for any updates to the Package Manager UI and install them if available.
    2. Verify that the installed packages are correctly registered within the project files.
    3. Try restarting the Unity Editor or your development environment to see if the packages appear correctly afterward.
    4. If the issue persists, consider reporting it to the Unity development team for further investigation and resolution.

    If you need further assistance, please provide additional details or context, and I'll do my best to help.

    The Package Manager UI should not be caching package information between projects. When a new project is created, the UI needs to refresh its package registry completely rather than carrying over installed packages from the previous project. This bug causes confusion by showing some packages as installed when they are not actually present in the current project. It seems to be a regression introduced in version 2.1.0, as the behavior worked properly in 2.0.1. The root cause likely lies in incorrect handling of the package registry when switching projects. The Package Manager UI code should be reviewed to ensure the package registry is reset appropriately upon creating a new project.

    This bug appears to be caused by the Package Manager UI not properly clearing its package registry when creating a new project. Previously installed packages are being remembered even in new projects where they don't exist. This results in incorrect status being shown for these packages in the UI. The issue seems to have been introduced in version 2.1.0 and is not present in 2.0.1. It should be investigated further to determine the exact cause and resolved so that the Package Manager UI displays accurate information for each project.
