Tester report: the viewer crashes intermittently when changing one of the graphics settings in the Mesh section of Preferences → Graphics.

Known so far:

Intermittent: it doesn't happen on every change.
It isn't known yet which setting in the Mesh section triggers it (e.g. mesh LOD / detail sliders).
Platform and build: unknown yet.

Information to collect:

Which setting was changed, and from what value to what value.
Platform (Windows / Linux), GPU and release tag.
Alchemy.log from the crashing session. On Windows, the crash dump from %LOCALAPPDATA%\CrashDumps (see the AlchemyCrashDumps.reg LocalDumps setup), or the Event Viewer "Application Error" entry.

Likely area: live LOD / mesh setting changes rebuilding geometry while the Vulkan clean pipeline (ingest / mesh store) still references the old data.

Possibly related: #107 (Windows abrupt exit with no dump). Crash dumps for this should be collected per the steps there.
