Unless Vortex has been updated for patch 7 it won't work. I recommend this tutorial for getting BG3MM to work with patch 7:
If you haven't already, BG3MM was updated so make sure to install the latest version, and also update your script extender!
Think of BG3MM as an easy way to add files to the mod list, and the in game mod manager as the tool to decide what mods will be active and what mods will not. I have stuck to using mostly in game mods from the browser menu, but I do use a few clothing mods like Basket Full of Equipment, and other things like Tutorial Chest and a few weapon packs. I do not adjust things within BG3MM, as its easier to just import the downloaded files from Nexus or other sites straight into it and then adjust in-game.
The third party mod situation will be messy until the mod developers themselves update and fix their mods accordingly, so make sure to check the logs/comment sections under mod posts to see if they've been updated.
This is the tutorial I used to understand how to use BG3MM in case you are new to it, the switch between Vortex and BG3MM can be a little daunting if you're just a casual player like me:
Hope any of this helps in the slightest. Absolute worst case, you can still use vortex along with Patch 6 Beta which is an option through steam if you downloaded there!
