Ghost inputs on LCD during printing

What is the problem?
I connect my Raspberry Pi 4 and SKR E3 mini board using a UART connection . The connection works fine, but if i start a print and the heatbed and nozzle is ready, i have ghost inputs on my LCD. It's like someone goes into the menu by pressing the LCD-button, then it jumps to Z-baby-steps and then back to the infoscreen. I have no issues, if i disconnect Octoprint and start the print with the SD-card.

What did you already try to solve it?
In Marlin 2.0.5 i have try to change the serialport from 2 to 0 and i uncomment the serialport_2 = -1. I deactivated bt of the pi.
