I use it as a Datapack /warp-portals-1.3.12.zip in fabric 1.20.1 (like the picture, I made sure I installed it correctly.) When I put down crying obsidian, throw the ender pearl and sadly, there's Nothing happened, I get nothing, no wand no particles.

Then I tried using the mod warp-portals-1.3.12.jar, but Nothing happened yet.

I have added other mods like:
farmers-delight-fabric-1.4.3.jar
Terralith_1.20_v2.5.1.jar
tectonic-fabric-1.20-2.3.5b.jar
entityculling-fabric-1.6.2-mc1.20.1.jar
starlight-1.1.2+fabric.dbc156f.jar
sodium-fabric-0.5.8+mc1.20.1.jar
lithium-fabric-mc1.20.1-0.11.2.jar
indium-1.0.30+mc1.20.4.jar
continuity-3.0.0-beta.3+1.20.1.jar
DistantHorizons-2.0.1-a-1.20.1.jar

Hey @FishMystery ! I'll test it with those mods to check for incompatibilities, I'll let you know if I find any soon

Hey @FishMystery, I tested with those mods and it seems to work fine. Can you send your complete mods folder as a .zip ? Are you running on singleplayer or multiplayer?
If you're not comfortable sharing here, you can also send me on discord notnull_gabriel or email gabrielctpinheiro [at] gmail.com

Hey @gabriel-pinheiro I think I have found the problem. I deleted my mods one by one, and when delete this one: simple_quiver (https://modrinth.com/mod/simple-quiver), works warp_portals fine. Will you solve their compatibility problems? Very much looking forward to it thank you in advance :-)
I'm running on singleplayer
