Go to Launcher options and select your 1.13.2 profile.
Turn on the Game directory switch and enter a full path to a dedicated 1.13.2 game folder. I call mine saves1132.
Below is what my 1.13.2 profile looks like.
I have separate game save folders of each different MC major release so that I don't accidentally damage a world by loading it into the wrong release.
Attached is my Save folders list and the typical contents of a Game directory (folder).
By having separate Game directories you can have totally different resource pack lists and shader packs for each version you play.
