The muxer error is indeed mentioned but for Huawei devices 🤔 @JoshAtticus

Fixed in latest release!

Fun! Not really sure what else I can do to fix this to be honest.

I'm SO SORRY turns out I never actually included the fix in the latest release, I incorrectly tagged my commit for a different issue with this issue's ID, then later thought I'd fixed the issue even though I hadn't. This should be actually fixed for 1.6.5

This issue is also extremely similar to #108

No problem, I'll then try the new release.

Hopefully solved in 1.6.5! Please let me know if this is not the case!
