The ‘posts’ table in my Classic Editor is not displaying correctly

I’ve received the following message from WP on the above linked page: “There has been a critical error on this website”. The titles of the posts are displaying vertically, by each letter, on the Post Table.

ie: “each is” looking like: e

a

c

h

This appears only on the title column of the table. The other columns are normal I have been able to write and edit a new page on the dashboard, but the post is not appearing on my live website.

Browser: Safari Makebook Pro: Mac OS 13.6.9 2017 3 thunderbolt ports

The “Pages” table displays normally

Thanks for your help,

Lynn Moore
