Upgrading Target SDK level breaks Google Play Login

I finally managed to deploy my Unreal Engine game to Android with Google Play login fully functional.

After all that hard work and just after my production release, I am now notified that I have to upgrade my app to comply with some target API level requirements.

From November 1, 2024, my target API level must be API level 34, otherwise I won’t be able to update my app.

In project settings, I changed my “Target SDK version” & “SDK Api level” from 32 → 34.

This single action has now broken my google play login screen. Whereas my login screen used to appear, it now doesnt appear.

Can anyone tell me why this is the case?

Please note inspecting logs is impossible. I have compiled the engine from source and enabled logging but after weeks and weeks my android logs dont work.

I just found this on the unreal Android Development requirements page.

As seen above, I will need to recompile my project using Unreal Engine 5.4.4.

I will try it out and revert with an answer.
