Using the Block editor I’m not able to see or activate the Categories, tags and thumbnails panels.
I’m using a custom theme and all plugins are disables.

This is what it looks like in the block editor:

And when I go to Preferences -> panels there is no even option to activate those panels

However when I use the TinyMCE editor with the Classic Editor Plugin it appears:

Is this a bug?

Errors shown in the console: (In the block editor)

How can I fix it?
