How to unlock user data of my Huawei Honor phone without losing the data？

I have switched on my old Huawei Honor phone after a long gap. On the screen, I have a message stating below > Android system > * User data locked > * Password required after you restart the device > * Some features are disabled automatically for security I have given the pattern that I remember giving when I used to use it, but then it doesn't get unlocked, and it says incorrect pattern. I tried various other patterns, but they didn't work. Can anyone help unlock my phone without losing data?
