New Version on Storyline 360 is Unstable

Hi there, I experience crashing of Storyline 360 since thre month now on my HP Zbooks. One had Windows 10 and Storyline - newest version - crashed when I opened the player settings.

So I sadly stopped using Storyline on that machine and changed all my project files to anolder machine. 

Now, on my older Zbook, its still windows 8.1 I experience crashes first time today. I get very frustrated now. Even the newest Update doesnt change that. It will crash after some actions within one minute or so. 

This is the report:
