My post edit, post create, page edit, page create are completely blank pages (no WordPress navigation bar, no top admin bar). My widget page has the top admin bar and side navigation, but the rest of the page is blank white

Debug on showed no errors, PHP error reporting, same. Server log is clear of any errors

Things I have tried...

• Disabled all plugins, still happens
• Activated default theme, still happens
• Uploaded all base WP files (not overwriting .htaccess or wp-config.php) in /{root}, /wp-admin/ and /wp-includes/ with a fresh version in case there was something corrupted in update, still happens

Console messages below (from widgets, page/post is similar):

I had a similar problem and I found the solution in this post. Please have a look at https://wordpress.org/support/topic/block-editor-unexpected-error/

This can happen after a WordPress core update. Clear any caching (Cloudflare/Varnish/WP Rocket etc) and your browser cache, then try again.
