Premiere 2018 crashes while Launching: "Loading PlayerMediaCore.prm"
Hi,
about a week ago I bought a new graphics card (AMD RX570 8GB on Windows 10 64-bit).
Since then my Premiere 2018 won't start.
It opens, then loads as usual and when it says: "Loading PlayerMediaCore.prm" the whole process crashes.

I read another thread where someone had a similar issue and could solve it with a certain NVIDIA driver:
Premiere Elements 13 Crashing on Launch with GTX 1080
And this one, though it's 2 years old:
Premiere Elements 11 will not open editor - has stopped working
Photoshop however starts just well. I'm desperate and don't know what else I could do.
Perhaps there's a special AMD graphic driver for Premiere anybody knows?
By now I tried:
- reinstalling all Adobe clients
- updating the graphics card drivers
- updating Premiere
I really hope you guys can help me,
Jackson
