    that isn't a rollback file - rollback files have the word "fulldowngrade" in the title.
    The rollback OS for the 7Pro is > https://oxygenos.oneplus.net/Fulldowngrade_wipe_18821_190425_0253_user_fix_revision_MP_release.zip

    you will be rolling back from beta to the same build - the version of the beta you are on is irrelevant as it will be wiped.

    have you rolled back the correct rollback build?
    is the file named either "Fulldowngrade_wipe_18821_190425_0253_user_fix_revision_MP_release.zip" or "OnePlus7Oxygen_13.X.09_OTA_009_all_1909030312_1ef93ccad8ce4f9e.zip" depending on whether you have the 7Pro or the 7 - note some web browsers like the Firefox privacy one will append ".JAR" on the end which will mean that it is not seen, it needs to end ".ZIP".
    is the file download complete?
    has the file been moved from where you downloaded it to the root?

    Is there a downgrade package for Android 10 Stable to Android Pie? or will one of the packages mentioned in this post work. Thanks for any help.

    should be fine. the only difference in the rollback build is a workaround to the fact that the build number normally has to be higher.
