My suggestion would be to get the carriage out into mid machine with the power off. If it is at the service station now, it is locked. Power up and when the carriage moves away from the service station area, pull the power plug out. Then move the carriage manually to see what part of the carriage is hitting the frame. It is possible to clip the ink tube crane in wrong and I suspect that is the problem. If so, disconnect the ink tube system from the carriage and re-install.
If you can’t puzzle it out, send a photo and I will try to identify the problem.
