Tacx Neo smart bike power problem

I have a Tacx New smart bike where suddenly got problems with bike giving very high. resistance. This made it impossible to pedal.

This is both when bike is connected to power and un-plugged.

Firmware is updated.

I have now just received a new replacement body and dis the swap of parts.  And have same issue !!! ??

So really confused what issue can be ?

Any thoughts ?
