Google Play Games Services crashes my game at startup every time.

I've tried the latest version 0.9.62 and a previous version 0.9.50 but it's the same every time.

I initialize the service at void Start, and then sign in. But when I try launc$$anonymous$$ng the game on a phone, it doesn't even start.

I've linked my app in the developer console, if that's any help. I've seen every single answer on Google, most of them mentioning adding /u003 in the Android Manifest, but that's been fixed in the newest version. And then they're mostly from 2017 even.

I've deleted and reimported the package multiple times just in case. No dice. When I remove everyt$$anonymous$$ng Google Play Games-related, the game runs fine.

Is anybody else experiencing t$$anonymous$$s? Am I missing somet$$anonymous$$ng here?
