My laptop with 8GB RAM and intel i5 processor used to work smoothly, but after 2 beta updates (Cumulative Update for Windows 11 Insider Preview (10.0.22623.1037) (KB5021304), and Cumulative Update for Windows 11 Insider Preview (10.0.22623.1028) (KB5021866)), my laptop has lost its performance and has begun lagging. It fails to run even small programs. Also,
the taskbar has a black shadow as in the attached screenshot. Can someone help me with the issue?
