Illegal Instruction in Hello World Program

I have an Assembly file called "main.asm" which has the following code:

    section .data
    hello: db "Hello World", 10
    helloLen: equ $-hello
section .text
    global _start
_start:
    mov rax, 1
    mov rdi, 1
    mov rsi, hello
    mov rdx, helloLen
    mov rdx, 14
    syscall
    mov rax, 60
    mov rdi, 0
    syscall

But when I assemble and link it with:

nasm -f elf64 main.asm -o main.o && ld main.o -o main && ./main

It gives me the following output:

This is weird because it worked for several days printing out "Hello World" and now it's this.

The problem was that my PC changed the Terminal from Kali Linux which I'm using with WSL to "Git Bash", it created a main.o and main file but it couldn't give an output from the file.
