 * In the site editor, whenever I try to edit a block style, I get an error. I copied
   the error bellow. Is anyone else having the same issue? I running the latest 
   wordpress on a local environment.

 * Deactivate all plugins and switch to a standard theme such as TwentyTwentyFive.
   The error should then no longer occur. You can then reactivate your theme and
   check whether the error occurs again. If not, reactivate the plugins one by one
   until the error occurs again. This should enable you to identify the component
   responsible.
 * Alternatively, the error could also be caused by an add-on in your browser. Try
   using a different browser or a private browser window where no add-ons are activated.

 * Hi. Same errors as the OP when I try to style (Edit Site) the font faces, the
   font sizes, and especially the font size for the buttons.
 * I deactivated all plugins. Result: same errors.
 * I am using a child theme of Twenty Twenty-Five, so I activated the parent of 
   Twenty Twenty-Five, Version: 1.4. Just pure WordPress. Result: same errors.
 * I cleared the caching. I am using a local install so can’t share a link.
 * Thought you might want to know.
