Flutter error Execution failed for task ':app:processDebugResources'

Issue

Edit: solved, I went to Android Studio, File -> Invalidate Caches/Restart -> Invalidate and Restart, also did flutter clean for the projects. Now both run as expected. Finally.

I created a sample flutter app doing flutter create and then ran with flutter run. This is odd because a week ago I did the same thing and had no problems. And another weird thing, I created an hour ago another sample app and doing flutter run on that works perfectly fine. Same sample app, same code, but one has errors.

I am using Android API 31, no change since last week. I found 5 posts on this site, some were saying to change gradle build version or something but I wasn't sure what it meant exactly. Both sample apps were created in the same night, no edits. I have restarted my computer but no luck.

Here is the output of flutter run:

Running Gradle task 'assembleDebug'...
