I am having the same issue that, this guy was having here (https://toolset.com/de/forums/topic/types-backend-fields-are-not-showing-up-after-wp-update-to-5-3/).

I was getting this error in my console, for just one post type (downloads)

bundle.add_or_edit.js:1 Uncaught TypeError: Cannot read property 'getCurrentPostId' of null
at Module.<anonymous> (bundle.add_or_edit.js:1)
at n (bundle.add_or_edit.js:1)
at bundle.add_or_edit.js:1
at bundle.add_or_edit.js:1

I found this question which talks about the problem => https://toolset.com/forums/topic/cant-edit-post-form/

Now the solutions given was to update, the type which I did. In the changelog also I can find,
<bold>Fixed a WordPress 5.3 compatibility issue that was producing a JavaScript error on the Edit Post page.</bold>

After applying this fix, I got rid of the error, but the problem is still there. What should I do?

Could I take a look at your site to check for myself what is happening on the backend edit screens?

I will mark your next reply as private so that I can get log-in credentials from you—you may want to create a temporary admin user for me to use that you can later delete. And be sure to have a current backup of your site.

There is nothing to show on the Download posts edit screens, other than the title.

In the settings for the post type the post content editor is disabled. (Toolset > Post Types)

And the custom field group "Download field" is not active. (Toolset > Custom Fields)

My issue is resolved now. Thank you!
