Aristois eliminates information
every so often the aristois restarts everything, the waypoints are deleted, the configuration of my keys disappear, the configuration of the mods in the same way, the only thing that remains when it restarts is the list of servers, I use Aristois 1.16.5
After updating or just randomly? Your config is probably corrupt. You should delete it (.minecraft/libraries/EMC/mcversion/configs/) and then it should not happen anymore.
