The voltage I get over the capacitor is around 3.2V. This voltage stays consistent when I'm flashing and no matter what baud rate I try. I've also tried different capacitors and I get around the same voltage level.

The Hardware Design Guidelines recommend placing bypass capacitors of 0.1uF on some of the VDD lines for the ESP32-S3 (EG 0.1 uF on VDD_SPI). Whenever I place these capacitors on my circuit, I get an invalid head of packet error when trying to flash the device over UART: Configuring flash size... Fl...
