I'm using your TrashSlot mod for my pack. Looking at the log, it seems to be present, but it does not load (see screenshot below).

• OS: Linux Mint 19.3
• Minecraft: 1.15.2
• Forge version: 31.1.88
• TrashSlot_1.15.2-11.0.0

There's a keybind to toggle it, it's probably toggled off right now.

Yup, that was it. Thanks!
