Add-Ons Button is missing from the bar with Options

Today I logged in and it made me download the game again as if I uninstalled it. I have curse forge all updated for my Add-ons but when I log into WoW, there is no option for Add-ons anymore. They are suddenly gone. I have been playing for years but this is a new one for me. I have seen a couple other people post about this problem back in 2019, but nothing for 2025. Is there a new update that took it away?

How do I fix this so I can play normally . I don’t like the game without the add-ons.
