**Modlist**
too many..

Start with the linked mclo.gs crash report and the listed Minecraft 1.20.1, GhostZ 1.0.3, and Fabric API versions. Reproduce the shift-click crash with the reported setup, then narrow down the mod conflict using the full mod list. Done means the triggering cause is identified and the server no longer crashes.
