Launcher does not allow login, despite correct username and password being entered

[loogidood]

• I searched the issue tracker for other issues covering my case
• This is a Launcher issue. (Usually if you can reproduce it with a fresh instance)

Describe the bug
So, my friend was trying to log into GDLauncher for the first time. However, when attempting to log in using the normal sign in and the microsoft sign in, they said invalid username or password. However, he has a mojang account that was migrated to a microsoft account, he was able to sign in using the same password and username he typed into GDLauncher into the minecraft vanilla launcher and it worked perfectly fine, and he even changed around his microsoft account as well (which was before logging into the vanilla minecraft launcher). Due to the nature of this bug and me or him having no idea how to even understand Javascript, we wont be able to provide any sort of errors in the code. And it seems to be isolated to just his computer as when I relog, it works perfectly fine. I looked it up on the github, checked I believe issue #710 and it didn't help out at all.

To Reproduce
Steps to reproduce the behavior:
Due to its isolation on his computer, its not really possible to reproduce, but all he did was:

1. Type in login information
2. Click Login Button on either the normal login or the microsoft login.
3. "Invalid username or password"

Expected behavior
He expected himself to be logged into the launcher

Possible solutions
No clue, I'm sorry if this is a bit of a useless endeavor, but I have no idea how to even begin to help fix his problem.
