We're seeing a similar error in our code. Appears to be a combination of AGP 8.6.0 and Kotlin 2 needed to hit it.

private fun Intent.stripUnwantedFlags() {
    // Explicitly remove the new task and clear task flags (Our browser activity is a single
    // task activity and we never want to start a second task here).
    flags = flags and Intent.FLAG_ACTIVITY_NEW_TASK.inv()
    flags = flags and Intent.FLAG_ACTIVITY_CLEAR_TASK.inv()

    // IntentReceiverActivity is started with the "excludeFromRecents" flag (set in manifest). We
    // do not want to propagate this flag from the intent receiver activity to the browser.
    flags = flags and Intent.FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS.inv()
}

All 3 lines then hit:

Must be one or more of: Intent.FLAG_GRANT_READ_URI_PERMISSION, Intent.FLAG_GRANT_WRITE_URI_PERMISSION, Intent.FLAG_FROM_BACKGROUND, Intent.FLAG_DEBUG_LOG_RESOLUTION, Intent.FLAG_EXCLUDE_STOPPED_PACKAGES, Intent.FLAG_INCLUDE_STOPPED_PACKAGES, Intent.FLAG_GRANT_PERSISTABLE_URI_PERMISSION, Intent.FLAG_GRANT_PREFIX_URI_PERMISSION, Intent.FLAG_ACTIVITY_MATCH_EXTERNAL, Intent.FLAG_ACTIVITY_NO_HISTORY, Intent.FLAG_ACTIVITY_SINGLE_TOP, Intent.FLAG_ACTIVITY_NEW_TASK, Intent.FLAG_ACTIVITY_MULTIPLE_TASK, Intent.FLAG_ACTIVITY_CLEAR_TOP, Intent.FLAG_ACTIVITY_FORWARD_RESULT, Intent.FLAG_ACTIVITY_PREVIOUS_IS_TOP, Intent.FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS, Intent.FLAG_ACTIVITY_BROUGHT_TO_FRONT, Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED, Intent.FLAG_ACTIVITY_LAUNCHED_FROM_HISTORY, Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET, Intent.FLAG_ACTIVITY_NEW_DOCUMENT, Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET, Intent.FLAG_ACTIVITY_NO_USER_ACTION, Intent.FLAG_ACTIVITY_REORDER_TO_FRONT, Intent.FLAG_ACTIVITY_NO_ANIMATION, Intent.FLAG_ACTIVITY_CLEAR_TASK, Intent.FLAG_ACTIVITY_TASK_ON_HOME, Intent.FLAG_ACTIVITY_RETAIN_IN_RECENTS, Intent.FLAG_ACTIVITY_LAUNCH_ADJACENT, Intent.FLAG_ACTIVITY_REQUIRE_NON_BROWSER, Intent.FLAG_ACTIVITY_REQUIRE_DEFAULT, Intent.FLAG_RECEIVER_REGISTERED_ONLY, Intent.FLAG_RECEIVER_REPLACE_PENDING, Intent.FLAG_RECEIVER_FOREGROUND, Intent.FLAG_RECEIVER_NO_ABORT, Intent.FLAG_RECEIVER_VISIBLE_TO_INSTANT_APPS

The initial report (comment#1) seems like a dup of b/352609562 (internal link), and fixed at https://cs.android.com/android-studio/platform/tools/base/+/f88d11033727f891bcc2a7a1cbbeb109c7d5dd0f I believe it's available in AGP 8.7.0-alpha02+

However, comment#2 indicates that there are more kinds of conversions we may miss... Let me double-check that.
