App crash on startup Unity 2021.3.40

Hello Im triying to update my project from unity 2020 to unity 2021
I deleted the library folder & configure again the editor.

*target API: 33
*firebase 11.6
*addressables 1.19.19

it builds correctly but crash instantly on start.
this is the debug:

Any idea what might be causing the problem?

Try development build.

Hi, I enabled development build & script debugging
but now fails on buid:

ok, I disabled script debugging and its build OK (with development build).
Yet, still crash on startup

Your app is using Play Core libraries for Asset Pack delivery that are not compatible with Unity.

Thanks, solved. looks like the play core package I was using on unity 2020 doesnt work on 2021.
I updated the package and now the app works fine.
