Hello,
when I try to connect to the WiFi with my esp32c3 I get this error and a boot loop...WHat can I do?

Check the supply voltage under load with an oscilloscope.
It's dropping down how can I solve this?

Use an adequate power supply (more than usual 500mA-USB, thick short cables/wires, power supply soldered instead of breadboard wiring, ...).
For more specific help show a picture of your specific hardware setup.
Use a energy buffer!
There is on the right side of the USB-socket a +5V and GND Pin, connect to this pins a capacitor to have a energy buffer. You can try 100µF.
I added to my ESP32-C3 SuperMini a 1000µF capacitor and did get now a connection to my router. For this process it needs a lot of current.

Which voltage do I need to use?
minimum 6V, better 10V
Which voltage do I need to use?
Simply connect this ESP-C3 to USB, so ethe capacitor will be filled with 5V.

A big capacitor at the 5V supply may damage the USB connector. The USB specification allows max. 10 µF.

Do you see the copper trace on the PCB, this is the current limitation. It works fine with 1000µF. If he is using 100µF this is totally save. Don't be such a pussy.
