I have just started android and I created an app that was running fine a few days ago now I am working on another app but I am not able to run that and now I’m not even able to run the previous one. now it's just showing Waiting for all the target devices to come online and then it says Gradle build finished in 830ms or like that!

To solve this-

Go to Device Manager>> Virtual and select launch AVD or from options select cold boot now.

That button in the popout panel, or you can always do Ctrl Shift A as usual and start typing what you're looking for!
