How to get Minecraft java to work with CurseForge

Hello,

December 2021 I have purchased Minecraft java. Because it was after 1. December 2021, I could not purchase it with a Mojang account, but only with a Microsoft account and so I did...

I downloaded minefract and I can play it, out of the box.

But I purchased Minecraft java because I want to play a Modpack with my family. When I try to launch the Modpack trough CurseForge it won't accept my Microsoft account. I don't know why.

I tried to login with an account I have borrowed from some family. This is an old account, which was created in Mojang. If I use this account everything works fine.

This lead me to, there are something wrong with the link between Microsoft account and Mojang, so modpacks does not work.

Is there others who have seen this issue and know how to solve it?
