Unable to log-in and play even in single-player

Today (3rd of June 2026) I have been trying to log-in to the launcher for hours, Microsoft accounts work and I was able to log there, I can check my mails, I am online and can do anything except play Minecraft which is absurd since I play in single player, I always have a message saying the launcher wasn’t able to establish a connection to Minecraft services. I’m unable to play in my single-player world, I can only use a demo version of the game that is limited in time, even though I own this game since something like 2011 and used to be able to play offline. This is very frustrating.

Edit : I wasn’t able to check other issues tracked in here before I wrote this, I saw it was reported by numerous people already, so feel free to delete duplicate reports such as mine.
