[2022] Eivor is falling and then desynchronises when entering Asgard during the quest 'Binding Fate'

Re: [AC Valhalla bug](/topic/102323/ac-valhalla-bug) Travel back to Asgard to defeat Fenrir after already starting the mission. I have patiently waiting for a fix for this for over a year and now the glitch has changed again for a third time. Now as soon as i travel in I am falling through the sky with no way to stop it or fast travel just falls until we desync. Do not have a previous save to go back on since I have already completely the entire game plus all DLC apart from this. Please help I have video and pictures but discussion board won’t let me upload them.
