Zwift not Responding when using a power meter

Hi

I’ve just bought a new laptop as Zwift stopped working on my old one - no idea why.

My Zwift Hub is working fine on the new laptop but I prefer to use my Stages Power Meter as I’ve always trained with it. However, when i try to connect the PM, Zwift stops responding and I have to use ctrl/alt/delete to escape.

Any thoughts would be very welcome.

Thanks

Ali
