Run Project on Android Error

Hello everyone.

I’m coming to you for the first time because I have a problem that I can’t figure out.
Under Unreal 4.26.2, I try to launch an Android project directly on my smartphone.

Only, once the package is finished compiling everything, the game launches, the UE4 logo appears, then crashes. And here is what the logs give me as an error message:
