The same thing happened to me 2 days ago... same exact behavior, first I displayed the screen as yours, you could no longer see the cursor position, then after closing the app several times, the cursor came back, but the position was wrong, it was hundreds of meters behind, in all this the voice directions were correct... maybe it is the case that the developers take a look at this post, I would not want it to be a problem of the new update... I always have the phone near the CarPlay on the handlebars, I doubt there were any disconnections... and the phone signal was constant...
