I am having trouble editing my header and footer template parts on wp block editor (child theme 2022). I keep getting an error message “saving failed”.

I am building the site with elementor(not a pro version) and using the wp block editor for the header and footer. I had no problem creating it- but I cant save any changes I want to add now.

The error message is recent problem. I cant add any template parts as well- there seems to be something wrong with the block editor
Is there anything I can do about this?
