Why I got to pus so hard on the pedals to start riding ?

Hi, last time that I tried a free ride I had to use all my weight to turn the crankset and start my session. I didn't tried anymore to not injure myself and went on freestyle workout but you can change your power only with the companion app and not zwift click. What could I do to reduce the resistance at the beginning ?

I got the cog v2 on Zwift Ride/Zwift Hub
