After 6 months of annoyance, I solved the problem. Its Malwarebytes. Do you have that installed? Its specifically the pay version (Malwarebytes Pro). If so, simply uncheck "enable malicious website blocking" under "protection". Some people have to completely uninstall the Pro version and use the lighter one, but the above has worked for many, including me.
