Title is as it says, it is not working for 1.16.5
Could you update for 1.16.5?

Can confirm, not working in 1.16.5

I fixed it.
I opened the reach-out-1.0.0-1.16.4.jar file with WinRAR
Then I double-clicked on the file named fabric.mod.json
Then I edited this part:

"depends": {
"fabricloader": "\u003e\u003d0.10.8",
"fabric": "*",
"minecraft": "\u003e\u003d1.16.1"
},

to this

"depends": {
"fabricloader": "\u003e\u003d0.11.6",
"fabric": "*",
"minecraft": "\u003e\u003d1.16.5"
},

Saved the file and let WinRAR update the jar file.
I also renamed the jar file to reach-out-1.0.0-1.16.5.jar
Now it works in Minecraft 1.16.5

I also got the mod working with Minecraft 1.17.1 by doing the same thing as above.
