Laughting Leader's BG3 Mod Manager works perfectly, there was an error with the modsettings.lsx file when moving from Patch 6 to 7. To fix old mod load orders you need to delete the [i]modsettings.lsx[/i] file found here: [i][b]C:\Users\<your-username>\AppData\Local\Larian Studios\Baldur's Gate 3\PlayerProfiles\Public[/b][/i].
If you installed third party [i]dll[/i] files you should remove them, the only [i]dll[/i] based mod that is known to work is Norbyte's Script Extender (he has been working with the engine from years ago and it's rock solid for both users and modders).
In Patch7 you can also keep some of the older mods installed, some don't work anymore but the majority does.
I would not recommend using vortex or nexus mod manager to handle BG3 mods, in the past it has been the worst of the herd.
