Xcode installation stuck

I tried to install Xcode on my iMac M1. I got stuck at ‘Installing’ after the download. I read online to restart the computer so that’s what I did. When I got back there the app was ‘Downloading’ but it was stuck at 11.68Gb/11.68Gb and the bar was not moving. Now it’s back to the original ‘Installing’ and the bar is still not moving.

Before that I also tried a solution to disconnect from the App Store, delete Xcode and start again. It also didn’t work.

I just got my new iMac and I feel like I’m already messing up with my system files. There are two Xcode apps and the first one is already working if I double click on it, it's so weird!
