Update…I started a new course using the “Create New Title” and then selected the “Accessibility” option. This title has a video in it with captions enabled, and is configured to Use Web Accessibility Settings . I published the course (using v18.0.2) and uploaded to SCORM. When I reach the video page and attempt to go full screen, I get the same result in Chrome. Both the course and LMS window crash with the messages I included earlier in the screen shots.
If I republish this course to use the seamless player (that’s the only change…no modifications to the content), full screen video in Chrome works just fine!
