Morning Heidi. Yep, Tea was able to replicate the crash and reported a bug on the issue. Lectora development is looking into it, but it’s not clear if/when a fix might be released. Tea said this thread will be updated with any new info or status.
Have you tried updating your Chrome? I only ask because after I updated my Chrome yesterday, the error changed. Instead of crashing, I just get a black screen when going full screen video. I think Carl stated the Chrome update fixed his issue.
