For some reason Windows 10 stopped working for me. I had to robocopy my C disk which took me several days... I "upgraded" to Windows 11 and everything seems to working okay.
The mesh is split up again, so it's not so easy to copy the weights from one mesh to another. That's why her top straps/frills look weirdly metal. Originally it would be part of her dress, with it's own shader. I'm forced to join the top with her body so that it moves along with it. The dress has their own weight numbering names so I can't copy the weights from her body and then join it with the dress.
I've included the blendfile, because sadly I'm thinking of changing my Patreon up a bit.
