What can I do if my screen lock pin no longer works?

I have a problem, my Huawei cell phone has performed an automatic security update, now my device wants me to enter the pin for the screen lock. Unfortunately that doesn't work. I keep seeing that I have entered the wrong PIN. Is there a way I can work around this or reset the password without losing all data?

Thank you very much

PS: Yes, I entered the correct pin and not my SD card pin, it's really only about the screen lock

Don't know how to fix that.

So my Samsung wants to have the SIM card pin FIRST after an update and only then the device pin

You can work around it, but then you have to reset the entire phone and everything will be deleted until further notice

I entered my SIM card PIN, but I can no longer unlock my screen

Okay, you didn't write that.

Can I save the favor data externally without having to access the screen? Unfortunately, I have absolutely no idea about it

If you had the find my device app, it would still be possible, but it would not work without accessing the mobile phone
