Notes (Required)

If you happen to share a .minecraft instance with another user (in my case /home/user1/.minecraft/PrismLauncher/instances and /home/user2/.minecraft/PrismLauncher/instances are linked to the same place in the filesystem) the user who ran the game later will not be able to run the game due to all configuration files having 644 permissions. chmoding file permissions to 664 solves the problem, but only temporarily. Sometimes configs are re-written with 644 permissions and this will crash the client for the second user.

Can confirm. Also the library will crash when max_user_instances is too low in sysctl which is a similar problem in terms of UNIX.
