[5.x]: Link Field broken after update, entry edit pages inaccessible

What happened?

Description

I've started developing a Craft website on Craft 5.0-5.2 (unfortunately I can't remember) and then upgraded to Craft 5.4. I used URL fields, which became Link fields after the upgrade. Since the upgrade all backend edit pages of entries using the link field are broken and creating elements with a link field isn't possible anymore. I've tried nuking the database, expecting a faulty migration. I've changed the link field to something else and back, but the error persists.
The link field is used within card elements in a matrix in my case. I tried attaching it directly to the entry itself and it doesn't error/crash the edit page, I can even save URLs or phone numbers, but not assets (they get removed when I try to save them - no error showing up though).
Steps to reproduce

Create a link field and attach to an entry type, that is used within a matrix field.
Create an entry with the link entry type
Call to a member function isEmpty() on null error
Expected behavior

I can edit the entry and work on link fields, saving, deleting, editing etc.
Actual behavior

The error when I try to create an element (via the button) with a link type in it within a matrix block of a new entry page:
All entry edit pages that where created prior to the update and contain a link field now show this error when you try to access them:
Error
Call to a member function isEmpty() on null
