Occasionally, the launcher loses the primary account details. Any secondary accounts remain fine.

Additionally, I realize that this is just MCL-12347 , but because no action was taken by commenting on that one that it is still occurring after two, felt like longer, months, I decided to open a new ticket. It appears to happen most frequently when the launcher updates itself.

Furthermore, I think MCL-13965 is a case of someone else running into it, but not speaking english, so it didn't come across the same. Especially because this report was on the same launcher version that my first posting of it reoccuring was on.
