Came back but all of my stuff is gone...(need help)

I came back to this game after multiple years. I had multiple accounts in the top rankings with really good builds. I decided to check whats new but when i logged into my 2nd main account i found my inventory completely empty. Not even the beginner stuff was left and i can’t build a mechn to start over. So i literally can’t play the game on this account and i am afraid of logging into my other accounts. Does anyone know how to fix this or to prevent it from happening to my other accounts?
