The status stopped working after this error occured.

Caught error when decoding packet (op: 2, length: 37)

I've received the same stack trace (as the commenter above me). For what it's worth, I am wondering if something about RPC has changed? I noticed that another plugin/mod that I use for Minecraft to show status over Discord via RPC has also broken. Could be coincidence, but...

Discord Details:

Stable 166505 (fec0a45) Host 0.0.22 Linux 64-Bit (6.1.3-Arch1-1)

I'm on Arch Linux/EndeavourOS currently - will try to see if I can replicate this in Windows later on.

@russjr08 I think something weird happened. Also in my case right around the time the error went off I got cloudflare blocked from Discord's API for an hour so I couldn't even open the client
