TUMBLEWEED after updated kernel from 5.5.11-1 to 5.6.0-1 can't load KDE.

Today my Tumbleweed update kernel from 5.5.11-1 to 5.6.0-1 , I found an issue can't load KDE GUI and boot to terminal console after reboot.

And I could load KDE well by bootloader option to opensuse Tumbleweed , with Linux 5.5.11-1-default.

Please help ...
