GIFT-Format questions and JSON-error

GIFT-Format questions and JSON-error

We are experiencing a problem in using questions from the question bank. One of our lecturer added a new question using GIFT format into the question bank. Since that time he is getting the following error when he want to add some question bank questions:

JSON.parse: unexpected character at line 1 column 1 of the JSON data

The deletion of the question from the question bank does not do anything. He is not able to use any questions from the question bank.
We are using the Moodle version 3.5.2 together with PHP x64 v.7.2.11 under IIS.

Maybe someone has an idea where the problem is?

Those JavaScript errors are not very helpful. Are there are other error messages, e.g. in the PHP error log on the server?

In my case the problem source was a missing question type.
There were existing questions with the missing question type, then later likely the question type plugin was deleted. This is why the error appeared.
