Error on startup

Hi,

I have encountered this error upon startup.

pi@raspberrypi:~/projects/keyboard_mouse_emulate_on_raspberry $ sudo ./boot.sh

The same happens when I start it with sudo. It's a Raspberry PI 4.

Before starting mouse and keyboard client, you have to use this:

sudo ./server/btk_server.py

Let me know if it works.

The error message is still there.

I have the issue. Has anyone found a fix?

I use a Raspberry Pi 3B+ with RaspberryPi OS 64bit and a Logitech G403
