Plugin crashes on startup if collapse toolbar is set to "all"

[DraconicMentalist]

Describe the bug
As stated above, the plugin crashes when starting discord if collapse-toolbar is set to 'all'.
It produces this error message:

TypeError: Cannot read properties of null (reading 'querySelector')

The full contents of CollapsibleUIconfig.json in the plugin folder:

{
    "version": "12.0.0",
    "collapse-toolbar": "all"
}

Deleting "collapse-toolbar" from causes the plugin to start normally again, so that seems the likely cause.

To Reproduce
Steps to reproduce the behavior:

1. Open settings.
2. Set Collapse Toolbar Settings to "All"
3. Restart Discord
4. See that plugin has crashed with the error above.

Expected behavior
The plugin starting normally when enabled.

Desktop (please complete the following information):

• OS: Arch Linux
• Discord Version: discord-canary-electron-bin, 0.0.618-1
• Enabled Theme(s): RadialStatus
• (OPTIONAL) Enabled Plugins: Only this one.
