Printf function doesn't work in for loop

Getting Help

I’m making a Brainf**k interpreter in Golang.
But there is a strange bug in my program,
and I can’t find its cause.

func Execute(code string) {
	program, err := Compile(code)

	if program == nil {
		panic(err)
	}

	for i := 0; i < len(program); i++ {
		e := program[i]

		switch e[0] {
		case dec_ptr:
			if ptr <= 0 {
				ptr = mem_size - 1
				break
			}

			ptr--
		case inc_ptr:
			if ptr >= mem_size-1 {
				ptr = 0
				break
			}

			ptr++

		case decrease:
			if memory[ptr] <= 0 {
				memory[ptr] = 255
				break
			}

			memory[ptr]--
		case increase:
			if memory[ptr] >= 255 {
				memory[ptr] = 0
				break
			}

			memory[ptr]++

		case output:
			fmt.Printf("%s", string(memory[ptr]))
		case input:

		case loop_start:
			if memory[ptr] == 0 {
				i = e[1] - 1
			}
		case loop_end:
			if memory[ptr] != 0 {
				i = e[1] - 1
			}
		}

		// fmt.Printf("%d, %d, %d, %d, %d\n", memory[0], memory[1], memory[2], memory[3], memory[4])
	}
}

Here is a main function in my program with the bug.
When I use go run . or go build, ./<program-name> to run my program, it doesn’t print result.
But when I use VS Code debug tool to run it, it prints result.
I can’t find the cause of that! Please help me!

Here is BF code that I used to test, the bug didn’t show another BF code.
