Flutter <optimized out> message while debugging after upgrading to 3.10 [duplicate]

Question

When I try to debug a Flutter app in Vs Code, it hits the break point fine, but when I mouse over any variable to see its value, I get "< optimized out >< error >: < Invalid params >" tooltip. This started after I upgraded to 3.10 from 3.7. Happens both in macos and ios debugging including simulator and actual iphone.

I tried the steps below with no help:

1. flutter clean
2. delete /ios(macos)/Pods
3. delete /ios(macos)/Podfile.lock
4. flutter pub get
5. from inside ios(macos) folder: pod install
6. flutter run

And I can get the values of variables with print statement, that is the only way I can kinda debug now. I also deleted bin/cache directory of flutter sdk.

flutter doctor -v:

The only thing that worked for me is downgrading:

flutter downgrade 3.7.1
