I couldn't find any reason for the crash
is it for a code or any other reason

Don't do

Serial.print("An interrupt as occurred. Total number: ");
Serial.println(totalInterruptCounter);
writeFile(SD, "/hello.txt", "Hello\n ");

from within an interrupt routine. That will 100% crash your application.
Instead set a flag and handle it from the loop() or from a task assigned to do it.

thank you
i need append data to my file every 1 second
is there any other way?

[beegee-tokyo]

You could run a task that is writing to a file. Inside the tasks loop you wait for a semaphore. In your interrupt routine you give the semaphore which will trigger your write event in the task.

Try to search for ESP32 tasks and semaphores to get examples
