Can not start a quiz

Hello,

After clicking the "Attempt quiz" button on the quiz page, a "Start attempt" popup window appears, which displays an image from the webcam and prompts the user to accept the condition "I agree with the validation process." The webcam permission is granted, and the image is displayed in the intermediate popup window. I accept this condition and click the "Start attempt" button in this popup window. After that, another window appears, showing the quiz title, the quiz conditions (e.g., time limits), and again prompts me to click the "Start attempt" button. However, this button is inactive. In the browser console, I see a message like "Starting Moodle session timeout warning."

In some quizzes, everything works as expected, and I can complete the quiz. In these cases, the final popup window, which displays the quiz title and conditions, does not appear. Instead, the browser console shows a message like "Starting Moodle session keep-alive" at the beginning of the quiz. I am using the latest version of the plugin 1.5.0 and the latest version of Moodle 4.4.4. The problem appears in the latest versions of Chrome, Firefox and Microsoft Edge browsers.

What could be the issue, and why does the popup window with the inactive "Start attempt" button appear in some quizzes? Thanks for the plugin.
