The objects’ settings can be accessed:

Any idea as to how we might resolve this?

The ILIAS is a git-current 8.10 (running on PHP 7.4), the plugin was updated to the latest r8 branch (from r8_dev).

Could this be due to a comment from a user since deleted?

Seems indeed that deleting comments like the one above resolves the error and makes the Content tab accessible again.

The underlying issue probably should still be fixed, though … 😌

Fixed in r8 & r9
