How do I fix this? Thanks.

Also add the latest.log with sites like https://paste.ee/

or add the crash-report without sniffer+

[Luis_ST]

Could be an issue with Rubidium, AoA3, Puzzles Lib, Aether or SnifferPlus.

If the error remains after removing these Mods, post debug.log from the logs folder.
Note, in some launchers you need to enable the debug.log.
