How to know which mods won't crash your game for MCM5

It's important to remember that the MCMV5 update came out on the 27th of Oct so any mod that was last updated before the 27th is using MCMV4,

but if there's any mods that were updated on or after the 27th then they should use the latest version of MCM being V5 making them safe to use on Singleplayer & Multiplayer!

Exceptions of using mods from before 27th is if they barely change anything at all in the files to cause any issues to make the game crash, for example like scenes being altered or the game font being changed.
