Wahoo kickr core 2025 clicking sound

After 2000km my wahoo kickr core 2025 start doing clicking sounds. I don’t think its a lock key problem because I think this is quite different than the previous generation.

Its become even lauder when the bike is on it. Also sometimes the sound stops for a bit then again appears. Any suggestions are appreciated. It will be hard to bring it back tot the manufacturer. I wasnt able to remove the bolt that holds the belt its ridiculously thighten. I remove the belt but the bolt couldnt be un tightened
