app crashes phone

[qtatspi]

Hello, the latest version of this app from Fdroid net.screen freeze deskcon_10.apk after install, all goes fine until I go into the accessibility service and enable deskcon, then my phone crashes! using a MotoG xt1045 first gen 4GLTE, and using the talk back screen reader, it still speaks, but I can't power off the device, am unable to remove the apk being as it appears stuck in some screen which I can't read. and since it's from fdroid and I can't even get to my home screen or anything, I have no way to uninstall it, being as stupid me hasn't enabled usb debugging yet and can't currently. Is there a way to force remove this apk remotely? or something? or somehow at least disable the accessibility service so I can use my device again? Running android 4.4.4. I can turn on/off the screen, turn up the volumes, and the back/home/recent apps button cause this device has no menu key, they all give vibrating feedback but that's about it.
