I was losing hope on the solution of this issue because GeForce experience kept on crashing no matter what I did, the error was:
"something went wrong
Try rebooting your PC an then launch geforce experience"
ERROR CODE: 0x0003"
After going through a lot of solutions, a fix suggested in the article from appuals did the job. I reset my network adapter and voila! Geforce experience turned on without any issues.
P. S: I don't usually post reviews but this time I had to, this was a very stressful problem solved after a long time.
