Working to restore access with Jincux, but until further update, you should uninstall blockland glass and support_updater to avoid getting served bad addon updates
Blockland glass has been taken down and the issue has been contained. You do not need to delete blocklandglass or support_updater anymore, if you haven't already.
If you reused a password for your blockland glass account, change your password on every other site you used the password on. I cannot emphasize this enough.
