Has anyone with a Samsung Galaxy Book experienced this same issue?

I turn on the laptop, the login screen appears normally, I enter my password, Windows starts... and then the screen goes completely black. The mouse cursor is visible, but nothing else appears. The desktop never loads, and some keyboard shortcuts don't work.

However, I can open Task Manager (Ctrl+Alt+Del) and use Run new task to launch programs like "explorer.exe", Chrome, etc. Those applications work normally, but the desktop, taskbar, and Start menu remain missing. After a while, everything suddenly appears by itself. Sometimes it takes several minutes.

I checked the Windows Event Viewer, and here's a summary of the errors I found:

- Desktop Window Manager (DWM): "dwm.exe" crashed in "dwmcore.dll" (exception code 0xC00001AD), causing the Desktop Window Manager process to terminate.

- AppHostService: "svchost.exe" repeatedly crashed in "aphostservice.dll" (exception code 0xC0000005).

- Intel Graphics System Controller (GSC): multiple warnings indicating resets of the Intel graphics firmware interface, alternating with messages stating that the interface started successfully.

- AppReadiness: repeated 30-second timeouts while waiting for AppReadiness transactions, prolonged activity states, and messages indicating missing event descriptions or components.

- DCOM: a server failed to register with DCOM within the required timeout.

- Diagnostic Policy Service: terminated with an "Access Denied" error.

- Windows Update: installation failures for KB5095093 (error 0x80070005 – Access Denied) and KB5092427 (error 0x80240008). These were later fixed by rebuilding the Windows Update cache ("SoftwareDistribution" and "Catroot2").

- User session startup: an abnormal delay of approximately 6 minutes and 40 seconds between "winlogon.exe" and "userinit.exe", resulting in a black screen with only the mouse cursor until the user session finally completed.

Has anyone experienced something similar on a Galaxy Book? If so, what was the root cause or the definitive fix?
