The teleportation does occur, but the player still takes damage.

Fixed in next release

thank you very much for continuing to update your mod
this latest update (2.3.0) came with some accidental problems

• Ender Pearl's trim is giving immunity to any type of damage to the Player (even Void damage)

To test, just equip one piece of armor with Ender material, and try to take damage

/summon minecraft:creeper

/summon enderman

the Player just doesn't take damage, he doesn't teleport most of the time, but he always teleports in rain and water (but without taking damage)

• and another problem I found, if you go in the middle of an ocean, with no blocks nearby, you get stuck in the water without being able to move to the sides, as it seems like the Player is trying to teleport but has nowhere to go.

my config:

even low values are giving you immunity

• also the skeleton's arrows are reflected

I tested it on an instance with only BetterTrims, TrimsExpanded, ModMenu, Fabric API and YACL on Fabric 1.20.1

@Bawnorton pinging you

I opened an issue about it - #53
