Xiao ESP32c3 cannot reconnect to esphome after power cycle

Hi there. I can confirm the same behavior.

The XIAO-ESP23C3 only seems to be started while connected to a pc and start a serial terminal. In my case “picocom /dev/ttyACM0 -b115200” on my Linux pc.
Only then, I can see the divice connects wifi by simply pinging its fixed IP address. I also see all the start and run messages in the terminal.
After exiting picocom the device is still running fine. Both pinging and control by HomeAssistant keeps working. But after a reset by the button on the device or by cycling usb-power it stays unreachable.

So I guess this is just some boot issue. Probably done by control of RTS/DTR when using serial communication.
Does anybody know the secret?

I will attach the esphome yaml file I use for this test:
