Unity.UI problems (Unity 2017.3.0f3 (64-bit))

Good day,

Recently I faced a problem - when I install a new build over the previous one, Unity.UI stops working properly. Several buttons don’t work at all and debagger doesn’t show any error messages. If I delete the application and install it again, everything is fine. Has anyone run into the same problem?

I’ve updated a few times and my project using UI was fine.

I updrade unity to 2017.f4 and problem gone ) subj solved
