Might be your RAR file is corrupted due to Windows 10 update which you did previously and hence you are facing problem while opening RAR file.
Once entered, the master password is valid until Win RAR is closed.
Close Win RAR and open it again after specifying the master password if you wish to see how protection works.
I even tried to extract those RAR files on other computer to but still I have the same issue.
It will be really helpful if somebody guide me to open my RAR archive.
