AdGuard Home uninstall problem

Hello,

i have uninstall the “AdGuard Home” add-on because of lots of problem with firewall and i still get warning :

Platform adguard not ready yet. Retrying in 180 seconds

what can i do to delete permanently AdGuard Home please?

I have try to reinstall but still 0.100.3 version of hassio, the add on says “This add-on is not available on your system.”.

Thanks for your help…
