EKF Critical velocity Black box warning message and multiple crashes with log files

I was testing todays daily beta build of PX4 but I could not launch. Every attempt at launching led to QGC saying EKF critical velocity error and something about black box. I have linked the logs from multiple takeoff attempts for review. The plane flew fine 2 days ago on the beta build.
