This why wrong if your small team cannot find then it is not a bug?Absolutely ridiculous. But anyway get back to stock firmware and install lineage 20.0 from scratch. That's the reason for safer side we ( our internal team tested on couple of old firmwares/new firmwares so no point of worrying about stock rom or may be something went wrong with your hardware level ) last we don't bother about any assurance on what went wrong because we don't release unless we use by our own hands.
