Sorry, there is no way to access your data without your master password and if you have forgotten your password, all your data is gone.
For us, security of your data is of utmost priority. Neither we have access to your data nor your master password as it is not saved anywhere not even on our servers. So, there are no backdoors to access your data and we can't get it back since it's encrypted with your master password. This is to ensure the best and optimum security to your confidential data.
To use Enpass again, you need to reset it on your device and start a fresh keychain.
