Resistance suddenly increased

Hey all,

Last week in the middle of a ride it felt like the resistance on my Zwift Ride suddenly increased and it hasn’t recovered since. Sorry that I don’t have more concrete numbers to back this but prior to this I would normally ride flats on gear 16 and cruise at ~100w with minimal effort and now under the same conditions I am pushing ~170w and feel enough resistance to stand up when I pedal.

I have a Kickr Core and have tried spindowns from the Wahoo app, disconnecting devices, unplugging devices, tweaking all sorts of settings and nothing has resolved the issue. If anyone has guidance that can help me out here I would greatly appreciate it, this has made riding MUCH less enjoyable.
