Storyline freezes with CefSharp.BrowswerSubprocess error

Actually, I did reply but the solutions offered did not resolve my situation so I set it aside. I still do not know what was causing the issue. After shutting down my computer and returning after the weekend, the problem seemed to be less frequent. Now, several weeks later, the problem has not returned.

Not the answer anyone was looking for. I wasn't using any additional virus protection software and I had temporarily disabled the Windows virus protection. Did not resolve the issue. The only thing I could think of as a possible cause would be that Windows was updating something in the background that I was not aware of. 

Luciana, the only advice I can offer is to make sure that your computer is not updating or running any tasks in the background that could be interfering with Storyline. Actually, I wonder if booting Windows in Safe Mode would help? That should stop any extraneous background processes. Leslie, what do you think?

I wish I had a better answer for everyone involved and I wish you luck in chasing down this issue.
