Comment:

 Hi Dbryrtfbcbhgf, sorry about the long delay. Other things bumped this off
 my radar.

 Unfortunately without a local repro my hands are pretty tied on
 troubleshooting this, but the stacktrace does provide a hint. Evidently a
 status change callback is hanging. Nyx has only four of those so next
 steps for troubleshooting this would be to comment those out one by one to
 determine which listener is at fault. After that we'll be able to
 troubleshoot why it's acting up.

 Since you have a repro but I don't I'll need for you to do this. For each
 of the following lines please add a '#' to the start. Nyx doesn't need any
 of these listeners (they're mostly to detect when tor restarts) so you can
 kill them all and quitting should work...

 https://gitweb.torproject.org/nyx.git/tree/nyx/panel/header.py#n56
 https://gitweb.torproject.org/nyx.git/tree/nyx/panel/graph.py#n443
 https://gitweb.torproject.org/nyx.git/tree/nyx/panel/torrc.py#n52
 https://gitweb.torproject.org/nyx.git/tree/nyx/tracker.py#n384

 Once we have a better idea of which listener is acting up we'll be able to
 narrow down why.
