In this and your more recent post Phone fails to start after OTA upgrade on S9: Custom binary blocked by OEM lock you have not fully made clear if you are part of this group ota-upgrade where the most significant thing is that this was the first ever OTA Upgrade of Android version from Android 8, Oreo to Android 10, Q on phones in the build type (or channel) stable.
