After Deepsleep, uart.read() get wrong Data.

[Dj-EKI]

I have a BLE module connected with RX to Pico TX, TX to RX Pico. I still have an Arduino Nano connected with TX to TX. Both devices fetch the information from the BLE module.
So far everything works great.
If my pico goes into deepsleep mode and is woken up with the pin, then the pico doesn't get proper data from the BLE anymore, but the Arduino gets real data.
The pico gets: b'\x00\x00\xf0\xf0\x00\xf0\x00\xf0\xf0\x00\xf0\xf0\xf0\xf0\xf0\xf0\xf0\x00\x00\xf0\x00'
Arduino gets: "Hallo"
Anyone know what's going wrong?
My Pico is a Waveshare RP2040-LCD-1.28
BLE modules TSL-03
i use Visual Code with Pico-go-W.
Micropython full source Code v1.19.1

UART_TX = Pin(4)
UART_RX = Pin(5)
uart = UART(1, 9600)  
uart.init(baudrate=115200,tx=UART_TX,rx=UART_RX,timeout_char=10,timeout=10)

EDIT: I just noticed that I set the baud rate to 9600 for the instance and 115200 when initializing. After Deepsleep it may go back to 9600 again. I set it to 115200 and now I can receive data without reinitializing the uart.

(Old Solution)
I found a solution. I reinitialize uart.

if WakeUp == True:
            uart.deinit()
            uart = UART(1, 9600)  
            uart.init(baudrate=115200,tx=UART_TX,rx=UART_RX,timeout_char=10,timeout=10)
            print("Deinit UART")
