Cannot revover account

Since the update my account was logged out. I never had to login before so i did not remember my password. No worries, I would be able to regain access with the forget password option. However, it states that it doesn’t recognize my username and thereby was not able to find my email adress. Can someone help me recover my account. I don’t want to lose al my progress I made the past year
Thank you in advance

On it.
