Hi Tri Tamado Yulianta,
Thanks for reaching out and I'm sorry to hear that you're running into this issue! I'm happy to help troubleshoot and have a few clarifying questions to start.
- Are you working from a local hard drive? We don't recommend working with files on a network drive as it can cause unexpected behavior.
- Is this issue isolated to one project or every .story file where you attempt to insert the Engage activity? If it's only happening with this one project, have you tried importing your slides into a new Storyline project?
If you're comfortable sharing your file with us, I'd be happy to take a closer look at what's going on. You can upload it here or share it privately in a support case. We'll delete it from our systems once troubleshooting is complete.
