[Flutter] Why my Flutter app don't run? BUG! exception in phase 'semantic analysis' in source...

I tried to figure it out, but I couldn't even find how. Please help me.

When I try to run my first flutter app this happen:

FAILURE: Build failed with an exception.

* What went wrong:
Could not open settings generic class cache for settings file 'C:\Users\Angel\Downloads\Codigo\Flutter\first_app\android\settings.gradle' (C:\Users\Angel\.gradle\caches\6.7\scripts\1fnwrr8g4rohfp291nvlxj5qe).
> BUG! exception in phase 'semantic analysis' in source unit '_BuildScript_' Unsupported class file major version 60

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan
to get full insights.

* Get more help at https://help.gradle.org

I already tried with a physical device and the emulator. I try with "flutter clean". flutter doctor -v say all is good.

If it's helpful here is what comes out when running 'flutter run -v':
