Can't Start new game 2 years ago

Every time I try to start a game I get this error message,

The operation was canceled.

All my achievements and their unlocked items/characters from Events are gone :( 2 years ago

As the title says. This is the 2nd time this has happened, whether I am logged into my amplitude acc on Humankind or even log out and log in again. All my achievements and any progress I had from the game events and their items and characters (like Da Vinci, 

Día de los Muertos, Holi) are all gone. All the stuff I owned from the events are gone. 

Since this has already happened before, I really dont feel like achieving everything AGAIN since the first time it wasnt a big deal to me. But this is the 2nd time now! If this keeps happening and I keep losing things and have to achieve them again, it's irritating and disheartening. :(

Please tell me how to fix this issue and get all my achievements and items/characters for all the events back or how to contact support team. I'd appreciate any help! :) 

Thank you in advance! :)
