zsh: IOT instruction  survive-cli

Desktop (please complete the following information):

• OS: Linux
• Version: 5.18.10-gentoo

Additional context
Have re-enabled udev rules (sometimes it seems like they may interfere with SteamVR so I have disabled an re-enabled them) and the same bug still occurs. SteamVR works without issue and after starting then closing it the logs are virtually identical. This bug never occurred before – my previous install before version 1.0 was rock solid – but now libsurvive always seems to fail with some kind of IOT instruction or another.

Hi,
Have you tried deleting
~/.config/libsurvive/config.json?

This worked for me - Fedora 37.
