Weird issues with WordPress after installing recent update

Hello, Posting here because I don’t have an account in the WP forums and wasn’t able to find a solution there.

Long story short, installed the new 6.7.1 update, updated my theme and plugins, and several things seemed to break.

Now, when I click to edit a post, content appears in the text editor. But if I try to use the visual editor, it’s just empty, with the cursor flashing at the top left corner like there’s nothing there. And if I click “quick edit” on any post, that post immediately disappears from the list of posts. Everything else shifts up instantly. But if I refresh the page, the post reappears and everything is right where it should be.

I also don’t seem to be able to edit some aspects of the site in general: if I go to “General Settings” and click a button like “Change Site Icon,” nothing happens.

I have 10 plugins installed in total, and have tried disabling each one in turn, waiting for a minute, refreshing the editor, and then editing and quick editing posts. Disabling each plugin one at a time didn’t find the issue.

Tried logging into WordPress in Chrome, Firefox, and Safari, so I don’t think it’s a cache issue.

At this point I’m just not really sure what to do or where the problem is. I did find this 2011 Stack Exchange post describing a similar “quick edit” issue, but doubt that’s my problem – not sure how to fix that if so.

Some threads suggested it might be the theme interacting with a plugin, but disabling each plugin didn’t work. I guess it could be multiple plugins causing the problems? Kind of at a loss.

Looked through recent posts here and top posts from the past month, didn’t see anything similar, but could have missed something.

Any help would be appreciated. Thanks
