TLDR; If you're crashing, please switch to beta.

Fixes

A recent Windows 11 update (KB5066835) created a bug in HTTP2 that causes VRCFaceTracking to crash after connecting to the VRChat OSCQuery HTTP handshake server. Microsoft currently is aware of a bug with HTTP2 and local connections.
There is a temporary fix in the beta branch. You may need to restart VRCFaceTracking when changing avatars.

Funny Side Note

If you've never explored it, the beta branch includes more features that haven't been pushed to the stable branch. There's new settings that allow you to tweak how your headset tracks your pretty little face.
