Spotify Web Player Widevine problem

Description of the issue:

Trying to enter the spotify web player but it doesn’t let me - It always says to Enable secure playback in your browser. (Already done it)
Tried to clear cache and browsing history.
Tried to uninstall and install.
Tried to manually install Widevine.
Problem still there.

I also tried with different browsers and the spotify web player is working without problem. (Firefox, Chrome, Edge and also Brave Beta)

Operating System and Brave Version(See the About Brave page in the main menu):
Windows 10 1903
Version 0.70.121 Chromium: 78.0.3904.70 (Official Build) (64-bit)

Additional Information:
It was working until 1 week ago - I haven’t changed anything.
