Can you help me?

Hi, i install unity hub and unity editor 2019 LTS, when i start a projet i recev the message "
Error Failed to add editor bundled package [C:\Program Files\unity editor\2019.4.22f1\Editor\Data\Resources\PackageManager\Editor\com.unity.formats.alembic-1.0.7.tgz] to the package cache:
zlib: incorrect data check
UnityEditor.EditorApplication:Internal_CallUpdateFunctions () "

i don't know what to do, because i have problem when i try to donwload an Editor

 

Looks like a package issue... Unity has lately taken to barfing tons of useless packages into projects and causing no end of horrible problems for users.

Try removing the complaining package using the package manager.

If that doesn't work, perhaps try reimport all.

If that doesn't work, try uninstall Unity and try reinstall it. We're using 2019 LTS and it does work.

 

Olá, tenho tentado instalar o Unity, mas quando faço isso não consigo instalar nenhum editor.

quando clico em quando em "gerenciador de pacotes" não há nada na lista, apenas "Erro ao carregar pacotes, consulte o console"
