Why WiFi transferring not working correctly in ESP32-S3?

Hii, I have the raw ESP32 S3 with a self-made Inverted-F antenna.
I can scan for different WiFis and can discover quite a some with fine signal strength.
I can not, still, connect to any WiFi. It tries to connect forever. Even when I get really very close to the router.
similarly, creating an AP doesn’t give an error, but the AP doesn’t become visible when scanning with other devices.

I assume there’s some error that prevents me from * transferring * anything.
What could be the issue?

Thank you in advance.
