This is affecting me as well with v1.19. I tried it on a server first, which was being killed by Watchdog after a tick exceeded 60 seconds. I moved to single player with the same seed and tried opening the underwater chest, and it did eventually open correctly without crashing, although the entire game stopped processing ticks during that time.
