I am Using ESP32-S3 and External Flash MT25QU256ABA1EW7-0SIT[FLASH - NOR Memory IC 256Mbit SPI - Quad I/O 133 MHz 8-WPDFN (6x5)(MLP8)].
Firmware is developed in Arduino framework. But after flashing i am getting below error

Since firmware is developed in Arduino environment so to make it work under esp-idf framework I am using VS code extension PlatformIO and also did memory partition according to External flash size(32MB), Still facing same issue.
I am attaching Partition file, main.ino, sdkconfig_defaults, platformio.ini for reference
NOTE :
On the same Board I tried to upload basic HelloWorld program from esp-idf framework, it worked successfully without any issue.
But when i am running my firmware which is using Arduino IDE and Libraries, I am getting error after flashing Firmware is not loading.
I also Tried with platformIO extension to take help of esp-idf framework in modifying sdkconfig still facing the same issue
Please look into the issue; your support would be greatly appreciated.
