When I deleted the 4 files it broke my website and putting the files back did not fix it. I did a restore of a backup, and that did not fix it. I had to get technical support from an expert and from Inmotion Hosting to resolve the issue with another complete restore, and those files are now gone, after the 6.6.1 update.
wp-includes/blocks/block/editor.css, wp-includes/blocks/block/editor.min.css, wp-includes/blocks/block/editor-rtl.css, wp-includes/blocks/block/editor-rtl.css
Thanks for your help!
Before I got your message, I restored to the previous day’s backup inside Go Daddy.
