Try specifying a profile for the respawns, perhaps it fails to find it -> errors.

Good afternoon, thank you for your suggestion. Assuming that is the issue, I am unable to understand what to write there, or I may not even understand its purpose. If you could provide more details, I would appreciate it.

Create a new respawn profile like you did for stashtraps, but specifically for player respawns (if you want the plugin to manage random respawns). By default it's "" (no name). If you don't want the plugin to manage player respawns, set Enable Respawn Management to false.
