Crash after commit [Add movieFragmentInterval options.] when enter in background

[al3x88]

Describe the bug

If I install version 2.0.0 everything works perfectly unless you can't record locally as for the change in this commit: f433315

If setup my SPM with this commit:

what happen is that, the first time I call (in viewDidLoad):

Task{ await mixer... }

and I put the app in background, it throw the error:

Incorrect actor executor assumption

and, if you are from the simulator it crashes, otherwise it restart from splash view (so basically the streaming is lost).

Note: if I comment all mixer occurrences and I test it works perfectly (unless does nothing since mixer is commented)

I tested extensively and I figured out that the behaviour happens after commit [Oct 31]:

4d19072

So most probably is related to some change happened on MediaMixer() on [Nov 1] here:

1e95f89

So currently I don't see any commit on ver 2.0.0 that allow my to record and going in background without issues.
Hope you can help me!! Many thanks for you amazing work.

To Reproduce

1. SPM: setup commit: f433315
2. When you are on IngestViewController.swift (or similar) put app in background
3. if you are testing from Xcode it will crash with error: Incorrect actor executor assumption
4. if you are testing without out Xcode it will restart from splash view.

Expected behavior

When app is set in background, it should be resumed without issues and keeping RTMP connection and view alive.
