is there any way to find the right one?
Your only option is to brute force the password but the problem with brute forcing is that you need to know something about your password and cannot do it otherwise. It is all about the number of passwords you have to test, if you don't know the length for example the number is going to be unlimited and recovering it is simply impossible. But you decrease that total count by eliminating as many cases as you can for example by knowing the length, the type of characters used (upper case, lower case, symbols,...) knowing certain phrases or characters that may be in your password,...
The encryption techniques used in encrypting keys and wallets are designed in a way that you can never brute force them if you know nothing about the password used in the encryption, otherwise they would have been insecure algorithms.
