[2022] AC Valhalla DLC suddenly became unavailable

Good time of the day ladies and gents. I decided to create this topic as the issue I'm encountering is quite weird. I bought the game quite some time ago not long after the release of AC Valhalla (approx after a week after the release). The initial purchase was made in the Epic Games and then transferred over to the Uplay launcher. I played through all DLCs available at the time of the release and had no problems accessing them. Now I decided to play the game again after several months and in the store page it shows me that my battle pass, and the DLCs which are Wrath of the Druids, The Siege of Paris, Dawn of the Ragnarok, The Ledend of Beowulf, The Way of the Berserker expansions are installed. But I can't access them and the quests that are attached to them. The obvious sign that something is wrong in my case is that I can't travel to Ireland which is a part of the Wrath of the Druids DLC. And I have already been there on my save. I have already had access to it and now I don't. Also on my save game it says that DLC content isn't available and I won't get access to it unless I bring it back (???). Frustrating. Please help sort this out. Thank you.
