Also what did you update "from v1.8.4 to v1.8.5"?
AFAIK, Spicetify Marketplace 0.8.5 is available for Spicetify-cli v2.16.2 for Spotify versions 1.1.85 to 1.2.6 (for Windows)
It'd help to say what versions of all three you have.
If you used the spicetify auto installer from ohitstom it might not be working, If you use it to uninstall then reinstall spotify normally and use the commands from here: https://spicetify.app/docs/getting-started it should work again. Just had this issue while updating myself
