Wlx-S will often show troubleshooting tips in the logs, so it's good to always check them first.
By default, Wlx-S logs into /tmp/wlx.log.
Another way is to run Wlx in the terminal with --replace. This will stop the Wlx process started by SteamVR/WiVRn and start a new one that can be monitored in the terminal.
Run Wlx-S in rust-gdb (or even regular gdb) to get more info about the segfault.
Attach this with the other logs that you have.
rust-gdb -ex run target/debug/wlx-overlay-s
Try starting wlx-overlay-s with these environment variables, to force-use NVIDIA GPU:
EGL_PLATFORM=wayland __EGL_VENDOR_LIBRARY_FILENAMES=/usr/share/glvnd/egl_vendor.d/10_nvidia.json __NV_PRIME_RENDER_OFFLOAD=1
This could also help with people having difficulties launching the WayVR Dashboard itself.
