The Database was cleared after reboot, there was also an error.
We have a method database - h2.

log error:

I tried to delete uuid players, the error disappeared, but there is no base.

Yatopia 1.16.5
LuckPerms 5.3.3 (but later we updated to 5.3.33)

Seems like your database has become corrupted in some way. I suggest reverting to a backup if you have any.

Unfortunately, there is not much I can do to help.
