KB5077241 broke wifi (Windows on Arm)

Installed the KB5077241 yesterday on my Lenovo Yoga Slim 7x running Windows On Arm (Qualcomm Snapdragon X elite). Windows 11 25H2 Pro.

After the install and reboot wifi no longer works. Device manager shows the wifi card as working. But the wifi button in task bar is gone. There is nowhere to choose show networks etc.

Uninstalled the update and everything works again
