Norton 360 error 8506, 421 issue recurring

Hi, Please help as i continue to get this error message when I keep restarting and rebooting. I have run malwarebytes scan as well as downloading and running the Norton Power Eraser Scanner both came back clean and no malware issues. I have rebooted a few times, I continue getting the orange button with the question mark noting attention and then autofix runs. Auto fix runs and then says repair installation successful but I continue to get the orange arrow. after restarting. I currently am on Windows Vista, running norton 360. What should I do at this point since I followed the instructions from norton power eraser? Any help you can provide would be great. thanks Norton 360 20.3.0.36 Error: 8506, 421 Windows Vista (TM) Home Premium 6002.18765.x86fre.vistasp2_gdr.130104-1437 Norton Autofix Results: 1 item(s) Installation :: Success
