Whenever I start the game all my campaign and achievements are gone and whenever I try to play, I'm stuck at the main menu

I recently updated StarCraft 2 with the latest patch and decided to play the game again with a friend after a year of not playing the game. When the game was finally patched, all of my campaign progress and achievements have disappeared. At first I tried ignoring the problem believing that it was a simply a server issue until the problem persists and I wasn’t even able to play with a friend for it won’t allow me to join a lobby let alone start one for it would only show a loading screen whenever I attempt to join or make one. I also tried playing vs A.I and replaying the campaign yet the game doesn’t respond. I have searched for possible solutions and have tried deleting my cache to uninstalling and reinstalling the game yet with no avail. Are there any more solutions for what has happened with my game? After many years this is the first time that this has happened to me and it happened after opening the game for a year.

I’m in the same boat here 5 years later - anyone come up with a solution? (No I didn’t change regions, no I didn’t change accounts)
