New minecraft launcher clashing with my xbox account

So whenever I log onto Minecraft with my Microsoft account it logs me into Xbox/Microsoft related apps with that account, that’s just a bug? I hope they resolve it or change it in some way so I can login to a different account on Xbox then a different account on Minecraft without having to keep signing in and stuff. Also how do I reinstall the old Minecraft launcher or find it on my pc, I deleted it after installing the new one

If you deleted the old launcher, then I don't believe there's a way to get it back. Also to answer your question, that isn't a bug. When Minecraft accounts were Migrated to Microsoft, your Minecraft account was converted to the Microsoft account you merged it to. This means, you can't use the Minecraft account to sign in anymore and only the Microsoft account will work.

Hope this helps.

It's not in the migration instructions, but after the migration, you have to ADD a NEW account, and link it to your Microsoft account. Startup will take longer, but it sure works.

On the login prompt in the java launcher, go back. You'll see the mojang account you had been signing into - ignore it, and add a new account to the launcher. Using the email address associated with the microsoft account you just migrated to, sign in with the email address and password of your microsoft account. It's not an elegant migration on the UX side of things, but it does work.

I don’t think the issue I’m having is Minecraft’s fault. It’s got to do with the fact that when I login to my Minecraft account through my Microsoft account it signs me into that Microsoft account of other apps such as Xbox and Xbox console companion. That’s what Im having problems with, because I have 2 emails associated with 2 accounts, one being my Minecraft Microsoft account and the other being my Xbox account. This is really frustrating and annoying as whenever I want to open Minecraft whilst I’m using the Xbox app it logs me out of my xbox account and signs me into my Minecraft Microsoft account. Hope I’ve made things clear and I hope they solve this soon

You can contact Minecraft support if there's a way to move your Minecraft license to the other email. I don't believe it's possible but it is worth trying.
