That looks like a “blockchain” wallet. If you are having problems with your account at blockchain.com you need to contact blockchain.com. They are a Luxembourg company. See https://support.blockchain.com/hc/en-us
If you have forgotten a password neded to “unlock” your wallet, you have lost all your bitcoins and will either never get them back or will spend many months and tens of thousands of dollars in the attempt.
