Additional Information

See this line

Modmail/core/config.py

Line 243 in 49330b4

duration_seconds = {"snooze_default_duration"}

The config should be in this group such that it will be attempted to be converted and throws an error upon setting with wrong values.
This causes an error upon trying to use most threadmenu commands as it fetches an invalid config value
