Trying to install HACS on Haos

Error loading addon: Addon cb646a50_get does not exist. This is the error I receive when I follow the link to install HACS Im running home assistant as the os when I plug video cable into my mini pc and my monitor it says waiting for home assistant cli to start boots successfully and I see the logo and everything else etc. When I use the ssh terminal app thing I click start then it says Advanced SSH & Web Terminal
The app seems to not be ready, it might still be starting. Do you want to try again? I click yes and it keeps looping this mesage Advanced SSH & Web Terminal

The app is not running. Do you want to start it now?

Any help pleaseee
