The connections from U5 to the motors is short and nowhere near that crack. One or more of the 4 control lines that go to U5 are probably broken somewhere. Those traces are on the top and bottom of the board and all run right thru about the middle of the Stick there. I'd remove the Stick first, because if the traces on the bottom are cracked there very well could be damage on the top side as well. This is all the further I'm currently tracing them out. I'd have to pull the SOIC board there or poke around with the DMM to see where they end up on the SOIC board points, but odds are you have a break on one or more of those 4 there somewhere.
That's the right spot, but make sure that it is only touching #19. I can't make it out from the pic for sure, but it looks like that RSX trace is possibly grounded out on the one next to it, which is ground, and grounding the RSX line would make it go -100% there.
@ Greedaycolt - Welcome. @ Rocky98 - It's for sure repairable. Three of those 4 connections are ground anyway. Easy enough to just scrape a little bit of the solder mask away, the green 'paint' that is covering the copper underneath it. Then bend over those 3 leads and solder them to the board there. The fourth connection is the LB button line, and you can run a wire form that one to TP19.
