Unable to find bundled Java version - no jrb folder

I have just installed new Android Studio Electric Eel and flutter stopped working.
Here's my flutter doctor -v:

I have already looked around and everyone seems to have the same answer, move jbr to jre. But I don't have jbr in my android studio folder. (My folder is also on E: but that isn't a problem since everything is migrated there). What should I do?

I had exactly the same problem.
WORKAROUND:
Browse to your Android Studio install directory in Windows Explorer
Copy jrb\* to jre
You can find more details here:
https://github.com/flutter/flutter/issues/118502
PS:
I had a simple Flutter project that worked fine 6 months ago. When I upgraded Android Studio to Electric Eel, several things broke:
A/S Electric Eel now installs its embedded Java to "jrb" instead of "jre"
WORAROUND: copy jrb\* to jre
My project happened to target SDKVersion 30; Electric Eel requires minimum SDK 31
WORKAROUND: hack your Flutter project's android\app\build.gradle:
android {
compileSdkVersion 30 => 31
targetSdkVersion 30 => 31
Electric Eel requires a newer Kotlin version
WORKAROUND:android\app\build.gradle:
buildscript {
ext.kotlin_version = '1.3.50' => '1.6.10'

I had this same problem and I downloaded dolphin again and all the problems were gone.

My Flutter apps keeps crashing on startup, so I decided to hook it up on Firebase Crashlytics and got the following stacktrace:

I do not plan on developing for the web, so didn't bother to download chrome as I don't use it as my browser.
Any ideas on why this is happening?

Try changing your flutter channel to master or beta.
flutter channel beta
OR
flutter channel master
and then clean your project and install your packages.
flutter clean
flutter pub get
flutter run

Android license status unknown. Try re-installing or updating your Android SDK Manager

My app were running absolutely fine before and I do not get what was the problem later on. There were no updates in any files. I got an error in D:\src-flutter\Flutter-Projects\testing_app\android\app\build.gradle file. I tried solving it using many links.

Hiding the obsolete packages does not give me an option of Android SDK tools.
Any help would be appreciated.
