Playing on a seed i found on a subreddit, im experiencing this same issue. Also takes a very long time to open the chest with the map inside. This issue does not occur on another seed i also created in 1.19.3
SEED: 743324574
COORDINATES: 470 63 -1828
EDIT: I've read in https://bugs.mojang.com/browse/MC-218156 that it is due to the boats assigned treasure chest being too far away, making the chest open slowly and bug the map. I tested other shipwrecks with a closer treasure chest without problems.
