Instant closes after starting => Unable to fetch authentication token

[AeilonGit]

When stating the .exe it just closes within a second with the exact message:
error creating Discord session, Unable to fetch discord authentication token. HTTP 400 Bad Request, {["email"password is invalid."], "password":[Login or password is invalid. "]}

It's my first time using it but apparently it's occurring with other users as well going by the YouTube comments of someone who made a tutorial. It stopped working at least a week ago, could be longer.

It is NOT a captcha problem.

I did for the sake of following directions but it still isn't working.

I'm also inputting correct login data since I copy/paste them from a password manager and same credentials log me in on other clients.

Auth token gives the same issue.
