Xiaomi 17 Pro Max - About Mi Mover App Bug

Wait 5 sec.

I'm using a Xiaomi 17 Pro Max. Mi Mover app keeps giving me errors. When I try to transfer data from my old phone to the new one, the connection is interrupted. (My old phone model is Xiaomi 14 Ultra). Because of this, I can't transfer the data. Mi Mover version is 4.5.5.5 I updated my device to HyperOS 3.0.306.0, but the problem persists. What is the solution?
