Hi @reace
If I have understood your concern correctly, and do correct me if I'm wrong, you are unable to restore your Enpass vault on your Windows PC as you are getting incorrect master password error? If that is correct, for quick troubleshooting, I recommend you check this highly useful troubleshooting guide.
If the instructions in the above link do not help, kindly share the below details with me and I’ll get this investigated for you -
The version of the Enpass app and OS you are using on your devices.
Please share a screenshot of any error message you are getting.
Do you have Enpass application on any other of your devices and are you able to access your data? Is the master password working on those devices or are you accessing the Enpass app through biometrics/Face ID?
The number of vaults you have in your Enpass app.
