You can check emulator authorization. Open the emulator and check if there's an authorization dialog asking for permission to accept the RSA key. If so, accept it. If the dialog doesn't appear, try deleting the .android/avd/YourAVD.avd folder and recreate the AVD. Another way is increasing emulator RAM. Open Android Studio, go to AVD Manager, select your emulator, and click on Edit. Increase the RAM size under the Memory and Storage section. I hope you can fix it.
