Hi @erossini
Are you viewing the “regular” WordPress posts? I’m wondering if it’s possible that the categories and tags got disabled for you? You can check (and enable) them at: “…” menu (top right) > Preferences: https://imgur.com/MBlz8aX then go to the Panels section and make sure the Tags and Categories are checked: https://imgur.com/4OGvUcn
In the Preferences both Tags and Categories are checked.

Hm, okay that’s weird. Are you still able to reproduce this if you turn off all your plugins and switch back to a WordPress default (Twenty*) theme?
I haven’t tried, I have a lot of visitors right now
If you can install plugins, install “Health Check”: https://wordpress.org/plugins/health-check/
On the troubleshooting tab, you can click the button to disable all plugins and change the theme for JUST you, while you’re still logged in, without affecting normal visitors to your site. You can then use its admin bar menu to turn on/off plugins and themes one at a time.
See https://make.wordpress.org/support/handbook/appendix/troubleshooting-using-the-health-check/ or https://rankmath.com/kb/check-plugin-conflicts/ for more information.
