Launcher won't start after changing Microsoft credentials

[Mondei1]

I had opened the launcher for the very first time and logged in using my Microsoft account, no big deal. After changing my Microsoft credentials online (so on Microsoft side, not inside the launcher) and restarting the launcher nothing happend. The process was idle in the background. So I directly started the launcher in my terminal:

Instead of crashing becasuse Microsoft wont allow access using the stored token anymore, the client should just delete the account and prompt the user to enter the login credentials again.

Deleting the accounts.json in C:\Users\XXX\AppData\Roaming.betacraft\launcher\ fixes the issue.

• Platform: Windows 10 64-Bit
