Flywheel blocks when tilting to the right

My NEO2T started to develop some problems: 

- grinding noise at higher power levels

-  sudden (huge) increase in resistance, even when doing low power training session 

I noticed that these problems are worse when titled to the right. Normally when you stop pedaling, the flywheel of the Tacx NEO2T would continue to spin for a while. But when I tilt to the right the flywheel immediately stops. It is also impossible to start pedaling again then. When leaning, it keeps on spinning nicely. 

I have tried removing and reinstalling the disc, looking for any metal particles, but without success. I do notice that the magnets show quite some wear marks, like they have been rubbing against other parts. See photo attached. 

Any idea how to fix this?
