I am new to the ESP32 world and recently purchased an ESP32-S3-DevKitC-1. However, I am facing several problems with my project. Here is the list of issues:

Wi-Fi Connection Problem:
I am having trouble connecting to Wi-Fi. I always need to press my finger on the top part of the ESP32-S3 for it to connect. If I don’t, it stays stuck in a loading mode. Moreover, even when it connects to Wi-Fi (by pressing my finger), the connection drops as soon as I remove my finger.

5V Pin Issue:
I am unable to use the 5V pin. I need to supply 5V to some sensors, but I can’t get any output from the 5V pin. I tested it with an LED, but the LED doesn’t light up.

Wi-Fi Handling Issue:
I often encounter problems with Wi-Fi handling. With the code I’m using (I’ve commented out most parts for testing), it runs fine as long as I don’t touch the top part of the ESP32-S3 with my finger. However, if I touch it, it connects to Wi-Fi but immediately reboots the program (the first serial print statement, “Ask your question: …,” gets printed right before the reboot).

I know I’m new and might be making mistakes. Please feel free to point out anything I’m doing wrong. I am open to learning and improving. Thank you for your help!
