Forgot Huawei p30 lite pin?

So I forgot the 6-digit pin of my Huawei P30 Lite and wanted to reset it soon. Emui then tells me system update failed or something, because I probably haven't done an update yet, but I can't do it because I can't get into my cell phone. So someone knows what to do. It doesn't matter whether my data is lost from the cell phone, the main thing is that it's free.

Forgot pin

The device is stolen. I know the solution. But I don't help with stolen devices.

Now would be my first suspicion.
