ERG not working Kickr Windows 10

I’ve been using Zwift for a year with no issues. Yesterday for the first part of my workout ERG was all over the place. It resolved about 15 minutes in and I chalked it up to a temporary glitch.

Today it was worse, but still only seemed to happen early on (this time it lasted about 20 minutes).

My Kickr is the newer version so you don’t have an option to do a spindown manually. Is anyone else having this issue currently? Is it a Zwift issue or a Kickr issue? Thanks for any help here.
