SEED XIAO ESP32C3 does not start after power is plugged off and in again

Hi,
When I upload my code, the programm starts running and everything works fine. But when I cut off power for a short moment and put it on again (externally or PC), the code does not get executed anymore. I have to plug power off and on again many times to make it work. Pressing Restart does not change anything.
Unconnecting the USB-C, pressing Boot, reconnecting the USB and letting the Boot button go afterwards does help, but there must be a way to fix this problem. It would be extremly unreliable if you have to restart the board like this every time after power got cut off.
(also it has nothing to do with the code, the same behavior showed while making a LED blink)
Maybe I have to put a capacitor somewere? Has anyone had this problem as well? I did not find much about it on the internet.
