1 month ago After some research through closed topics, I identified the problem as this line: #define USE_HSPI_PORT. Now everything works correctly. I am attaching the code for User_Setup.h.
`// Setup file for ESP32S3 with ST7789 display

Hello everyone!
I have an ST7789 display with the following pins: GND, VCC, SCL, SDA, RST, DC, CS, and BL. I am trying to use it with an ESP32-S3 development board. While the display works great with a Raspberry Pi Pico, I can't get an image when using it with the ESP32-S3. Additionally, after uploading the example code, my ESP32-S3 goes into panic mode. I have attached a picture and the setup code. If you can help me, I would greatly appreciate it.
// Define the display driver and type
define ST7789_DRIVER
// Define the display resolution //#define TFT_WIDTH 240 //#define TFT_HEIGHT 240
/* Define the pins for ESP32S3 + St7789 used for the display
define TFT_MISO -1 // Not connected (MISO is not used in this setup)
define TFT_MOSI 11 // (SDA) Data out to display
define TFT_SCLK 12 // (SCL) Clock out to display
define TFT_CS 10 // Chip select control pin
define TFT_DC 9 // Data Command control pin
define TFT_RST 8 // Reset pin
define TFT_BL 7 // Backlight pin (optional, can be controlled via software)
// Power control settings (optional)
define TFT_BACKLIGHT_ON HIGH
