I have the same problem. I’ve figured that I can pull the cable to open the latch until she goes in for service next year. Fairly common issue on the forums. If I can get warranty/goodwill great. If not i’ll Stick with pulling the cable for what it’s worth.
I had same problem, just undid the latch and could then see cable, which was like bike brake cable, but mechanism not great and had just come loose. Think now fixed but easy enough to resolve & no idea why it would take 8 weeks for a part to arrive..............nip down to local bicycle shop and get a new cable would be quicker
