Android Question Apk without 'android:exported' property set

I get an error uploading my app on store (with targetsdk 31 (btw it gives me an error trying to install on phone)
android:targetSdkVersion="31" app not installed because package is not valid
android:targetSdkVersion="30" all working but tomoroow google will remove all appe with 30 or less... what i can do?

Now i upload the apk generated with 31 (not installed in my phone and taken from object folder and get this error from console:

You uploaded an APK or Android App Bundle which has an activity, activity alias, service or broadcast receiver with intent filter, but without 'android:exported' property set."​

The manifest is:
'This code will be applied to the manifest file during compilation.
'You do not need to modify it in most cases.
