UE-55700 - level change hangs if synth component is playing, is there a way to get a diff?

We’re running into the same problem but also with VOIP audio since that’s using the synth component.

Is there anyway to get a diff of the changes UE-55700 fixed or possibly even a patch for this since it’s targeted in 4.21 but that I suspect won’t be in the git repo for awhile.

Thanks
