Microsoft Abruptly Terminates VeraCrypt Account, Halting Windows Updates

I have encountered some challenges but the most serious one is that Microsoft terminated the account I have used for years to sign Windows drivers and the bootloader. You can see below a screenshot of the message shown when I tried to sign in. - MOUNIR IDRASSI (VeraCrypt Developer)

I don’t fully understand how VeraCrypt depends on MS for the release of their app on Windows. Can someone explain like I’m 5.

Either way, this is extremely alarming. We should be able to easily install any apps we want on our devices. I hope Louis Rossmann covers this.
