Game launcher goes crazy

Oh, no! Something went wrong, and we couldn't connect to the Minecraft services. I've just got Minecraft Launcher from the official minecraft page. During the installation process I checked if my microsoft account in Microsoft Store was attached, updated app itself and then continued downloading game files. After, I logged in launcher with the same microsoft account and finally made it to the launch page. But everything was significantly further from what it should look like. My avatar wasn't been depicted, there was only some error icon showing up. But the main issue is that I couldn't connect to the minecraft services so the only two ways i am able to play the game is offline or its demo version (watch the video below). It seems that I'm not the only one who faced with such problem but I haven't seen anybody giving a solution so far. Is it connected to the Java & Bedrock merging together? Spending 24 euro back in time and then wasting time on writing this. It's absolutely pathetic. Much more reliable using side launchers or curseforge which works perfectly fine.
