Cannot solve MILP with Barrier method + Crossover

Hello,

I'm still pretty new to optimization, so please forgive if my question may be obvious. I am able to solve my model relatively quickly using the Barrier method and Crossover=0 when I run the model as an LP. However, when I turn on certain functions that make the model an MILP, I am unable to get a solution. It also seems that Crossover must be used to solve an MILP, is that correct? I tried setting NumericFocus=1 but this didn't help. As far as I can see, the model is jumping around the the same solution/objective space, but cannot converge. Any suggestions? My log with NumericFocus=1 is below. Thank you!
