ESP32-S3 trouble connecting custom board

Hello,
I recently attempted to build my own Microcontroller board using an ESP32-S3 and ran into some issues. I just received the PCBA from the manufacturer, but I'm unable to establish a connection between the board and my computer.

I tried connecting to the USB-C port using the internal USB of the ESP chip. Unfortunately, my computer is unable to detect the ESP chip. When I do `ls /dev/tty.*` or `ls /dev/cu.*` nothing shows. I also checked the system report and it's empty.

I have attached the schematic for reference. Did I made mistakes designing this or are there areas for improvement? And if there is no error in the schematic, why can't I connect to the device?

I think you're missing a pullup resistor on CHIP_PU.
