Morning all I've had the same issue. I bought the aircraft from the ini-manager this morning, installed it for 2024 and the same issues as above. The EFB was fine, however there was nothing working with the plane. The buttons/switches interacted correctly but did nothing. I followed the steps above and deleted the manager and re-installed but nothing. I then noticed that when selecting the plane in the menu there is a "no cabin" option which was selected. I changed it to the "cabin" option loaded in and all working fine up to now fingers crossed. Hope this helps.
