Flutter: FAILURE: Build failed with an exception

Question

Since the last update of Android Studio (today is 23th of August 2020), each time I create a new flutter project I can't run it. Even if I do not modify a line of code and only create a blank new project then run it.

All my previous flutter project can be run in my VD without any problem. But I can't work on new projects because of this build failure.

I emptied cache using the menu 'File/Invalidate Caches / Restart ...'
I upgraded Flutter using "flutter upgrade --force' then 'flutter run -v' like in this post but it did not work for me.

I learn flutter via courses online but I don't know what to do to solve this problem. Do you have a solution ? Thank you

Here is what happens in the console (with a new flutter application project):

Launching lib\main.dart on Android SDK built for x86 in debug mode...
Running Gradle task 'assembleDebug'...

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:mergeDebugResources'.

Try to uninstall and to do a new and fresh install. This error usually refers to changes made in source files without updating references or any other resources the compiler is expecting. There are many errors coming from this new flutter version after upgraded. — Rod

Thank you, I uninstalled Android Studio but the directory "Android Studio" in c:\programme files was still there containing a jre directory, so I renamed it to Android Studio-old. Then, I downloaded the last version of Android Studio from the official website, then created a new flutter project and ran it but the problem is still here with the same errors.... :/ — Steeve Bois

I also try to build the new flutter application project using VS Code, but I had the same messages — Steeve Bois

Delete the androidstudio folder from the C:\Users\Steeve\Documents\Flutter\ directory.
