While the exam is active, the edit button is disabled by default. There is also a comment in the code:
<!-- Only show the edit button if the exam has not ended. Disable the button if the exam is running -->
I'm not sure if we want to remove this protection mechanism? Please provide feedback.
In the event that we actually would want to edit questions during the exam, I can gladly create a PR that makes the button clickable during exams.

We need to keep this protection mechanism. Editing a quiz while someone is actively working on it, is not supported, because it can lead to database inconsistencies. This also applies for test runs of instructors during the quiz setup.

The reason is that during editing, you could easily delete answer options that are already references in submitted answers.

We could potentially allow some kind of limited edit support (similar to re-evaluate), but this is not easy to implement and currently out of scope.

I believe it is still possible to edit the quiz even though the button is disabled. You can access the editing website via the href of the “edit” button. Should we also stop the user from this?
We could also add a tooltip or something similar stating that editing is not possible while the exam is open to provide clarity to the user.

Hey @Hialus,
I can also see that other people might think the disabled edit button is a bug,
so I've added a tooltip explaining to them why it's disabled. It would be great if you could review the PR for me
as it only spans a few lines.
Thanks ;D
