The result is "Unable to detect manifest file."

Hi,

1. We are not Akeeba Support! Maybe you are using wrong version. For J4 should be v9.8.
2. Are you able to install any other extension with similar size (3M) ?
3. In Joomla language you can install also via FTP tool. In general it's Joomla thing. We don't touch Joomla core in quickstart.

So it seems that you have problem with Joomla itself. Maybe first update to J4.4.
