Describe the problem

Arduino board continuously dis/reconnects in the IDE. I cannot upload any sketch.

To reproduce

1. Open the AppImage IDE by running the ./arduino-ide_2.1.1_Linux_64bit.AppImage command in the directory
2. Connect the Nano 33 BLE Sense
3. The board constantly disconnects and reconnects as shown in this video Screencast from 2023年07月12日 12:40:49.webm
4. This is the console output that is constantly repeated
