Can't Export H.264 crash - everytime when switching AVI to H.264

Everytime i want to export my project, PP shows me to export as AVI File in the export window. But as soon as i switch to H.264, it crashes.

It is really getting frustrating, because everything was working fine before.

Everything was workinng fine till my last project. I tried to export it, but it didn't work. As soos as i hit the export button, it crashed.

So i imported the porject to an new project and tried it too. This time, the export window opened, but i could only export as AVI, which is not an option for me. As soon as i switch it to H.264 it crashes.

I saw in a youtube video that you have to deactivate your intel graphic device, but this also didn't work for me.

Does somebody have a solution for that.
