The same problem was encountered and solved with a few line changes. Check the Project code panel, and go to Gradle Scripts --> build.gradle file, Change 3 places: compileSdkVersion, buildToolsVersion, targetSdkVersion from 31 to 30 You'll notice a lightbulb hit occurring on modified lines, click and choose sync [to version 30]. The Android Studio will automatically download BuildTool V30 and change project settings. Now run the app. It works for me

First of all, I face this issue in Android Studio 4.2.2 and you not need to downgrade the SDK build tool 31 to 30 or not to change compile SDK version. The main problem is the two files missing in SDK build tool 31 that are dx.bat dx.jar The solution is that these files are named d8 in the file location so changing their name to dx will solve the error. The steps are below. For Windows go to the location "C:\Users\user\AppData\Local\Android\Sdk\build-tools\31.0.0" find a file named d8.bat. This is a Windows batch file. rename d8.bat to dx.bat. in the folder lib ("C:\Users\user\AppData\Local\Android\Sdk\build-tools\31.0.0\lib") rename d8.jar to dx.jar Remember AppData is a hidden folder. Turn on hidden items to see the AppData folder. For macOS or Linux # change below to your Android SDK path cd ~/Library/Android/sdk/build-tools/31.0.0 \ && mv d8 dx \ && cd lib \ && mv d8.jar dx.jar Now run your project...
