Reproduction Steps

I just downloaded Minecraft 1.16.2 from the Minecraft Launcher, booted it up once, installed Fabric and started to slowly update my mods list. I noticed the game crashed, because mods like Phosphor and Sodium haven't jumped to 1.16.2 yet, so I took them out. Then I noticed that even though all the mods I had are compatible with 1.16.2, one or more of them weren't working as the game wouldn't have crashed yet again otherwise.
I narrowed the culprit down to Lithium v0.5.1 for MC 1.16.2, as when I removed it, the game started to boot up again just fine.

Crash Report File

Well, there isn't one that I can find in my Minecraft folder, but there's the launcher_log.txt file

Additional Information

I think it's already mentioned on the launcher's log, but the only other mods I'm using are:
Blur, Fabric API, Logical Zoom, Mod Menu, NoFog and Roughly Enough Items.

They all work correctly without Lithium. Throwing Lithium into the mix is what causes the crash.

You downloaded the wrong .jar file. You want https://github.com/jellysquid3/lithium-fabric/releases/download/mc1.16.2-0.5.2/lithium-fabric-mc1.16.2-0.5.2.jar

Oh shoot, I didn't notice!

Yeah, the regular .jar works just fine. Thank you!
