Problems streaming protected content on Win 10

Hello

Please i am having a problem streaming protected content DRM (ex: amazon prime, Netflix etc.).

I tried to no avail to troubleshoot the problem. I literally tried everything on my mind to resolve it. 

1. I installed coupled of new web browsers/ updated existing ones (Chromium edge, Firefox, chrome and Vivladi)
2. created new browser/windows profiles.
3. clear cache
4. update drivers/windows
5. change the dns
6. update widevine
7. Many many others

Firefox widevinecdm crashes everytime i run a protected video

I am suspecting that there a required service that is stopped resulting the problem. When i restarted windows in safe-mode the protected video ran normally without issues.

Please i am wondering if someone can help me resolve this issue. I searched everywhere on the net and couldn't fix the protected streaming to run again.
