HomePod Mini: Random music at full volume after update

Hello everyone, I had just updated my Homepod Mini (gen one) to version 26.6. Ever since then it has been randomly ever so often playing music out of no where at full volume even when I'm not even in my Flat (note when i call Siri to stop it usually stops but after 40-60 mins it starts up again sometimes saying "ok here is...." and sometimes playing without saying anything).

It has been driving me up the wall (side-note purchased in 2022 so no warranty). I have tried to reset it and after the reset having it activate in a different room as it previously was. It has no Scenes set. Currently it is disconnected from Power for it not to cause anymore problems and annoying me.

I have heard of the Ghost touch issue, which I hope is not the case.

I hope anyone here can help me here, please ( I am kind of attached to this device ).
