Solved by myself: I deactivated the hardware boost, and now it works!
Brief description of the issue: Spotify doesn't start properly, there's just a black screen with some options at the top, but these don't help me in any way
Steps to reproduce the issue:
What steps you’ve tried already: Reinstalling
Your device and operating system: Win 10 64 bit
Type of Spotify account you have (Free/ Premium): Premium, but didn't get the possiblity to log in
The app version of Spotify you’re using: Current one, don't know the exact number, but problem appeared a few weeks ago as well already
Any screenshots, if they can help to explain your issue: That's all it loads
Thanks in advance!
