Black Screen Flickering and WiFi Driver Vanish Simultaneously

My Windows 10 device where the screen flickers with black flashes intermittently, and at the same time, my WiFi driver disappears from the device manager, causing loss of internet connectivity. This problem happens randomly and disrupts my work, and restarting the computer temporarily resolves it, but the issue soon returns. I believe that using the Windows 11 Installation Assistant might help resolve these glitches, as it could provide a more stable or compatible environment for my hardware. I am looking for advice on how to troubleshoot this flickering and driver disappearance problem effectively, and whether replacing or updating the installation assistant is a good step toward fixing these persistent issues.
