The CPU immediately crashes after saying "Calling app_main()", and doesn't say anything else, causing the USB UART module of the ESP32-C6 to stop working, so I can't reprogram it over USB until I reprogram it over UART. If I take away the i2s_channel_read, the CPU acts like normal. What's going on? Is my config off or is there something wrong with the ESP32-C6? Many thanks to anyone who can answer. Also, the GPIOs I turn on at the beginning of my code correspond to the PDN and TDMI pins of the audio codec.
My schematics are in the attachments.
