My current config, and when I launch element, it states what's in the title, and I don't know why.

You got an error because that is not valid JSON.

Try this:

{
  "showLabsSettings": true,
  "settingDefaults": {
    "custom_themes": [
      {
        "name": "ThomCat black theme",
        "is_dark": true,
        "colors": {
          "accent-color": "#cc7b19",
          "primary-color": "#9F8652",
          "warning-color": "#f9c003",
          "sidebar-color": "#000000",
          "roomlist-background-color": "#191919",
          "roomlist-text-color": "#cc7b19",
          "roomlist-text-secondary-color": "#e5e5e5",
          "roomlist-highlights-color": "#323232",
          "roomlist-separator-color": "#4c4c4c",
          "timeline-background-color": "#000000",
          "timeline-text-color": "#e5e5e5",
          "secondary-content": "#e5e5e5",
          "tertiary-content": "#e5e5e5",
          "timeline-text-secondary-color": "#b2b2b2",
          "timeline-highlights-color": "#212121",
          "reaction-row-button-selected-bg-color": "#cc7b19"
        }
      }
    ]
  }
}
