[2022] Wrath of the druids. Can't loot specific items submerged underwater

2 specific locations:

1. South-east of Dublin, locked door with a treasure map behind it. The underwater key cannot be picked up no matter what
2. Ulster, an island to the northeast, the deed to rebuild the northernmost trading post is in on skeleton in the cage, partially submerged. While I can open the cage, the deed itself cannot be picked up

What I did to fix the issue:

• reloaded multiple saves, including those prior to discovering those locations
• restarted the game
• restarted the whole DLC from England

PS5, the latest patch. Any suggestions are very welcome, I’m trying to get platinum and this bug prevents me to achieve it. Thanks in advance
