apart from that, a similar issue occurs when you try to script the default theme itself.

What I found to be working (at least in 4.0) is adding a .ttf directly as the default theme font via the project settings. I can't find DynamicFont when importing a font at all. Curiously enough Godot filters out anything besides .tres when selecting the default font, but switcht o Allow all files and choosing a .ttf just works.
