This stacktrace shows the cause of issue is the AudioMixer. I have not ever tried it on the Fedora but I assume that Unity don't support Fedora. Are there Unity apps working fine on Fedora?

Of course, I've been developing and using an application on Fedora for about 2 years and it worked great until I added Render Streaming and got this error.

@avicarpio Sure. We have tested on Ubuntu20.04 for this package, but not tested on Fedora or CentOS. We are going to add Linux distribution which compatible with RHEL.

FYI, Unity supports CentOS 7 but not Fedora36. However, these distributions are compatible with RHEL, so it works on Fedora coincidentally.
