Thank you for reaching out to us through the Community. I am sorry to hear that you are experiencing this issue. What is the error message that you are receiving when you access your Contacts page? Also, could you please provide us with a screenshot of the error message? To troubleshoot: try switching browsers as the issue could potentially be browser-related. Also, I suggest to use incognito/safe mode and see if that resolves the issue as well. Let us know if these troubleshooting steps work!
