The error is telling you what the problem is

Apps targeting Android 12 and higher are required to specify an explicit value for android:exported when the corresponding component has an intent filter defined. See https://developer.android.com/guide/topics/manifest/activity-element#exported for details.

That means, any activity your app declares should have a android:exported="true" (or false) and your app (more like some plugins your app uses) has activities without it activity#com.razorpay.CheckoutActivity.

So you’ll have to update those plugins to a newer version that adds that line or if they are unmaintained do it yourself.
the plugins looks like razorpay and onesignal, but there could be more.
