Forgot unlock pattern what to do?

I need your help.

I forgot my unlock pattern for my Huawei P20 lite. Is there any way to somehow unlock my phone? I've already tried the trick with the Google account, without success. But does anyone know about it and do other tricks on how I can unlock it without losing my data?

I have a lot of experience with it. And have already made devices functional again

Great, do you have any tips for me?

Can't you hold it up to the light and look where the fingerprints have wiped:-). Maybe you'll come back to it that way.
