I know this is an old very well documented issue with Android Studio but trust me I tried everything I found on Stack Overflow old threads (solutions from 2016, 2017 which quite obviously could not work anymore in 2021).

I installed Android Studio and when I start it, it doesn't run. I tried to set JAVA_HOME, JDK_HOME, STUDIO_JDK to both the JRE folder coming with Android Studio and with the the JDK installation folder under C:\Program Files\Java\jdk-15.0.2. I paid attention to run studio64.exe since my java -version say I'm running a 64bit version

java version "15.0.2" 2021-01-19
Java(TM) SE Runtime Environment (build 15.0.2+7-27)
Java HotSpot(TM) 64-Bit Server VM (build 15.0.2+7-27, mixed mode, sharing)

I can run studio.bat but the IDE doesn't show up, I simply have this

I see the initial Android Studio splash screen but then the process CPU usage goes down to 0% and the RAM keeps at 1GB. I see a process linked to the "hello_ar_java Android Studio" windows but I don't see this window.

Here a screenshot of the processes linked to Android Studio

So apparently the Android Studio is running, the initial welcome project started but is doesn't show up.

Check task manager for apps Or process consuming resources and terminate these, if you are not using them, then restart android studio this worked for me.

so turns out you can't have your JAVA_HOME environment variable pointing to your own installation of Java. It has to be pointing to the JRE that comes with Android Studio.

Step 1: Delete any JAVA_HOME and JDK_HOME environment variables

Step 2: Copy the path to the jre folder inside your android studio installation

Step 3: Create new JAVA_HOME and JDK_HOME environment variables with the value as the path copied in step 2.

Android Studio should now open. Worked for me.
