"sleep 5" doesn't delay script for five seconds [closed]

Question

When I use the sleep command and execute the script the sleep doesn't work. The code just gets executed without stopping for the expected 5 seconds. I've added big values for after sleep too but it doesn't work.

#!/bin/bash
echo "Hello World"
sleep 5
echo "How Are you?"

I also ran bash -x script.sh:

+ echo 'Hello World'
Hello World
+ sleep 5
+ echo 'How Are you?'
How Are you?

Also ran strace -o script.trace -f bash -x script.sh. Here's script.trace file's data.

I'm using Kali Linux on WSL. What's wrong? How do I fix it?
