    I have scoured the interwebs seeking relief. When I try to import certain packages into my new project I get the following error in my console window:

    Failed to import package with error: Couldn't decompress package
    UnityEditor.Web.JSProxyMgr:DoTasks()

    I'll answer the following questions in advance:

    1) Yes, I have ample disk space. 228GB free space on the partition where the asset is downloaded and 1.91TB on the partition where my current project folder is located.

    2) There are no non-English characters in the directory or directory path.

    3) My user account has full admin rights to both partitions and all sub directories.

    4) I have deleted and re-down loaded the offending assets multiple times. Delted from the %APPDATA%\Unity\Asset Store-5.x\

    -I have also opened the "UNITYPACKAGE" with 7zip to confirm it is not empty. HOWEVER, when I try to open the container within it I get a CRC error.

    5) Uninstalled MalwareBytes and BitDefender, rebooted and redownloaded.

    6) Uninstalled Unity and UnityHub, deleted the packages and redownloaded.

    7) I have also created at least 3 different blank projects to test the import, each with the same results.

    I have also run SFC /scannow and DISM /online /Cleanup-Image /RestoreHealth to make sure the issue wasn't my O/S.

    Lastly I have also sent requests to the developers of the offending assets. I have not recieved a response yet from either of them so I'm hoping perhaps someone in the community may have some insight they could share.

    If anyone else runs into the same issue, I cleared my GI Cache and was able to import the assets without issue.

    Edit > Preference > GI Cache then click clean cache button.
