Migrated Account Impossible to Login with Launcher-Resolved in Comment

I have just migrated over my account and have been trying to sign into my account in the Minecraft Launcher. I've tried signing in with Microsoft account information as well as my old Mojang sign-in information, but both have been completely unsuccessful. I am able to sign in using my Microsoft account on Minecraft.net with no issue, but when I enter the same information into the launcher it does not work.
