Started getting 90002 error code after 06/07/2018 patch update

When submitting a bug report, please use the below template and thoroughly fill out the necessary information.

I have been getting an error code 90002 since 06/07/18 after patch. I have tried everything I can think of. I have uninstalled launcher, reinstalled launcher, rebooted router, called ISP to reset router, closed all background windows and tasks, checked firewall/antivirus software, changed from D11 to D9 and back. I've done everything imaginable and still get a red ring, lag and then disconnect with error code 90002 since 06/07/18 after patch. I even tried WTFast, that didn't work. Lastly, I reset my computer to factory default. If ANYBODY can help it would be greatly appreciated!!
