yes. Or use external cp2102 or CH340 module (from ebay/aliexpress)

Try remove in device manager the silabs cp210x...
Then restart computer and check in device manager again.
if the device has an exclamation mark, install the cp210x driver

Then look for the error in the protocol, not in the esp32 UART hardware

what kind of ACK is it?
There is no ACK in UART serial data transmission, it is asynchronous data transmission between transmitter and receiver, there is transmission even if the receiver is not connected....

14 outputs PWM signal at boot

Check these variable definitions:
news_payload
n_payload

if you want to convert an existing card, this works:

What do you expect without a code sample?

your display: Technical specifications
Driver: ILI9341
You selected in setup file the
#define ST7735_DRIVER // Define additional parameters below for this display
comment this,
and select the
// #define ILI9341_DRIVER // Generic driver for common displays
or
// #define ILI9341_2_DRIVER ...

Hi!
What is the full verbose error message?
Check the path and filename of the file, do not contain special characters, spaces, international characters, etc.
