In steady flight at 190 kt, with flaps 2, no slats, there is lot of margin, I'd say. However you can approach stall angle if the deceleration is "very decelerated", with an AoA that is much higher than steady 195 kt flight AoA.
Maybe this is what happened?
Was there a "STALL, STALL" warning?
I had one, during sim, when I pulled up for missed approach with no flaps. Margins can be very narrow in flaps or slats jammed situations... I think they should include, among the many notes of the procedure, approximate pitch attitudes for Go Around.
