A reddit user "lskph5vg" solved the
bug. 
https://www.reddit.com/r/emacs/comments/v53jpw/xwidgets_cannot_render_local_file_on_linux/iby14j3/?context=3

This behaviour was first solved in stackoverflow by
"DisableGraphics". https://stackoverflow.com/a/71740957

This is a bug due to faulty MIME type database, which can be solved by
these commands.

rm ~/.local/share/mime/packages/user-extension-html.xml
update-mime-database ~/.local/share/mime

Which seems to have nothing to do with webkitgtk or emacs, the bug can
be closed.
