Yesterday, when I opened Minecraft Launcher, I saw message "Oh no! Something went wrong and we couldn't connect to the minecraft services". When I click "Try again", nothing happens. I bought Minecraft Java Edition in 2019 and in 2021 I migrated to Microsoft. After migration I hadn't got any problems and was able to play Minecraft. I reinstalled Launcher, java, deleted all files in .minecraft, but problem still exists. And yes, this is exactly the account on which the game was purchased.
OS: Windows 8.1 64-bit

Screenshots:
1) Notification about error and button "Play demo" instead of "Play":

2) About Launcher (last version for Windows 7/8)

And please sorry for my bad English. I don't have enough knowledge of this language
