I can't reproduce the issue here on my Arch Linux installation. But the thing is that the deep noise remover is one of the heaviest plugins. There is nothing that can be done on our side when it starts to throw these errors about the cpu being too weak for it. My Ryzen 9900x has no issues with it. But on weaker processors it is better to use one of the other noise removers.

and can't open again with same error as #4958 (QIODevice::write (QLocalSocket): device not open), only after rebooting I can open Easy Effects again.

I still wonder what it is that is happening inside Flatpak's sandbox. This bug doesn't happen outside it.

Removed "deep noise remover" and it does not crash.
