Unfortunately (appName) has stopped

So I downloaded Unity Editor's 2020.1.6f1 today and made a small app tried to build it made some bug about android SDK and NDK and gradle, so I redowloaded 2020.1.6f1 with it's SDK NDK JSK from Unity Hub, and remade the app from scratch, when I build it, it writes success, when I send the .apk to my mobile (API 4.4.2 and I set the API in player settings to 4.4) via USB I installed it, once I launch the app gives me that message Unfortunately, testApp has stopped, so I remade a new project and didn't add a single thing in it, and switch it to android and build it with all its normal set up, same thing, seen all the question which has the same title as mine, tried all for naught
