Wahoo Kickr Core 2 sound not normal

Hello,

I bought a Wahoo Kickr Core 2 + Zwift Ride.

After about an hour of use, the home trainer started making an unusual noise. It was loud enough that I could hear it with my headphones and a fan on. Here are two videos to show you the noise:

Pedaling, then coasting until it stops spinning: https://youtube.com/shorts/swgCTSfQ040

Spinning by hand: https://youtube.com/shorts/zh3AC9EqDl0

Do you know this problem ? I contact wahoo support, but I hope that I won't have to sent it back

Thanks ! :)
