Can connecting a 5V device without level shifting cause these errors?
Can connecting a 5v device without level shifting cause these errors .. yes it really can. I know that ESP32's UART pins are designed for 3.3V logic levels. So as you connected a 5V TTL device directly, the higher voltage was what caused signal integrity issues that you are facing. You should stop doing such cus over time your ESP32 pins will damage. The 5V signal is outside the ESP32's safe input range, causing the garbage values.
