Same or similar issue - getting a message saying 'Oh no, something went wrong, and we could not connect to the Mincraft services. Try again.'. Have been 'Trying again' for 3 days. Using MS account, migrated successfully, played after migration about 2 months ago. Tried to play 2 days ago, but after new launcher installation, unable to play (except in the demo mode). Switched accounts, changed my password, uninstalled the launcher, reinstalled, all with the same result.
