Can you specify your installed version of Android studio ?

Did you get a message in your phone as shown in 9:32 of the video?

We have used Android studio version 3.1.3 to record these tutorials.
There may be various reasons for not building the project:

1.Your laptop configuration should have the specifications as given under system requirements in the link.

2. Make sure Java is installed on your system.

3. Install Android Studio as per the instruction given in

4.There should not be drop in Internet connection while installing and building the First project. Some of the gradle may not be downloaded completely.

Exactly can't say but a Squirrel type Image is shown in my Android studio, you may get an idea from that Squirrel Image, which I have downloaded from the same website specified by you.
My phone has Android 11.
Yes I have JDK installed.
Internet was correct.
