Xperia X : Ui Stopped Working

[Eimen_anacreado]

Hello,

I Have Sony Xperia X ( F5121 ) turning on Android 8.0.0 everything is ok since years, but today surprisingly i have an Ui crash error ! ( Ui Has Stopped Working )
This error is up whene i try to Unlock my phone phone with Pattern.

I Try to reset and repare my phone with Sony Companion, that's work but whene i make an Android pattern to lock my phone the bug is back...

I don't know what's relation and problème with Android Pattern and UI Crash. So if someone have an idea or same problème that would be nice to share solution, thank's !
