Flux 2 tacx random resistance

I’m wondering if someone can assist me. I’m new to Zwift and tacx. I have the tacx flux 2 and am using Bluetooth to connect to my MacBook Pro. When cycling I randomly have crazy resistance spikes that don’t let up and I cannot continue to cycle. Iv restarted, reconnected and tried Zwift on my iPhone 11 and the same issue occurs. The issue also occurs if I stop a ride and then continue then the resistance makes it impossible.

Iv tried to figure the issue out but haven’t had any luck.

Any ideas?
