    $\begingroup$ I don't know whether this is causing your problem, but I note that the random-effect variance for your zero-inflation model is very close to 0. Also, I just caught the enormously negative coefficient estimates for the zero-inflation model, as @AlexJ points out. $\endgroup$ Commented Nov 11 at 22:25

    $\begingroup$ The zero-inflated component looks incredibly complicated. Look at the size of the estimates. I suspect you will have to drastically simplify it $\endgroup$ Commented Nov 11 at 22:26
