Black background

I exported the game to Android and downloaded it via my phone. when I downloaded it and opened it, I saw only a black background and after opening, the game lags and I have to restart the phone. how to fix this?

need to see your export settings, also which godot version you are using exactly (full version)

Version - v3.5.2.stable.official [170ba337a]

export problem

i have sdk and debug.keystore in settings

you will need to add debug key and debug user password to that, you can use unity’s debug store key

Where should i add debug key?

in the editor add sdk path, debug keystore here first

I add this with jdk21 from godot tutorial, should i switch this?
And i have sdk from android studio

i tried with the sdk one
