I can't run my flutter existing projects, what is happening?

I keep getting this error and I don't seem to find any help online. I am new to flutter, vscode and this whole programming world. Any help is very well appreciated. The thing is I can't run my previous projects but I actually can if I create new ones.
This is what it is printed in the debug console when I try to run my previous projects:
FAILURE: Build failed with an exception.

Try downgrading API level to 23.0.3. You can do that using Android SDK Manager and Android Studio or you can follow the instructions here.
Versions newer than 23.0.3 still have bugs.

Build failed ionic project execution failed for task : processDebugResources'

I used to build and run my project with no problems. But, now I have this error eevry time I run ionic run android:
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':processDebugResources'.

My Android SDK is updated, and so is ionic.
Any suggestions?
