Slides Advancing Automatically Without Triggers

I'm experiencing a recurring issue in my project: some slides keep advancing automatically without the user clicking the "Next" button. I've double-checked and there are no triggers set to cause this behavior.

It's really frustrating—I keep running into bugs with Storyline, and it's becoming difficult to manage. Now, on top of that, when learners go back to those slides, the content doesn’t load and slides appear blank. This is affecting the whole learning experience.

I've seen posts on this same issue from years ago and it looks like the bug had not been fixed or something... 

Any ideas on how to fix this?
