Thanks for this confirmation !
Well.. Do you have a previous backup of your device or using BlackBerry Protect for backup ?
If you don't have a backup then please try to boot on Safe mode ( it may multiple attempts to get success ) and delete that particular application , it will resolve your issue .
Or , if you have a backup or Unable to boot on safe mode then to resolve your issue you have to load the OS again , as you device is on a reboot loop it will not allow a simple reload , So , follow this KB to reload the device OS . But as I said this method will delete all data within your device memory .
