Flutter VS Code Emulator stuck at Running Gradle task 'assembleDebug' - flutter

Question

Since yesterday evening I've been unable to open my app in emulator. It worked fine till then.
Launching lib\main.dart on Android SDK built for x86 in debug mode...
lib\main.dart:1
√ Built build\app\outputs\flutter-apk\app-debug.apk.
It usually takes about 2 mins to open but it was just stuck there for like 15 mins. So I looked up for answers and the first one said to use gradlew clean and gradlew build. I did that and still was stuck but with another error.
Launching lib\main.dart on Android SDK built for x86 in debug mode...
lib\main.dart:1
Note: C:\flutter\.pub-cache\hosted\pub.dartlang.org\path_provider_android-2.0.12\android\src\main\java\io\flutter\plugins\pathprovider\PathProviderPlugin.java uses unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.
√ Built build\app\outputs\flutter-apk\app-debug.apk.
Then I tried an answer from a similar question here that suggested to do flutter pub cache repair. Still no luck.
Then I tried another suggestion from an answer here to upgrade flutter. I hadn't upgraded flutter for a couple months since so I did that but still the issue persists.
I read from a comment to a question here that when they run the project using flutter run -v in terminal it opened up after about 20 mins. So I started it and because my laptop is like 6 years old running 6th gen i5 with 8gb ram I thought it might take a bit longer. So I left it there and now after about 2 hours my terminal is stuck at:
I hit the question character limit so I put the terminal's output in
an online notepad at: https://anotepad.com/notes/3jri4gpc
I just closed the emulator and the terminal added this to the above

From [+7331895 ms] executing: in the first line after closing the emulator I can see that this was running for about 122 minutes.
I don't understand what's wrong here. Why did the emulator stop working normally all of a sudden?
How to make it work so that I can continue with my app development? Please help.
