Visual Studio 2022 and 2026 UI Freezes (Busy Cursor) After Closing and Reopening - Reinstall & Cache Clear Failed

Issue Description: Recently, Visual Studio has become completely unresponsive during or after debugging. The mouse cursor stays in the "Busy" state, and I cannot click any buttons or menus within the IDE. This happens with any project, not just a specific one.

Environment:

• Visual Studio Version: 2026 (18.3.1)
• OS: Windows 11
• Frequency: Occurs frequently after the first session.

Troubleshooting Steps Already Attempted (None Worked): I have already tried all standard solutions suggested in previous threads, including:

1. Running devenv /safemode (Issue persists).
2. Deleting ComponentModelCache and Cache folders in %LOCALAPPDATA%.
3. Disabling Hardware Graphics Acceleration.
4. Disabling Git Integration / Source Control.
5. Complete Reinstall: I uninstalled VS via Installer, deleted all related AppData, NuGet folders, and cache, then reinstalled. The problem returned immediately.

Critical New Observation: I found a specific pattern that might indicate a background process issue:

1. After restarting the computer (or signing out), Visual Studio works perfectly in debug mode.
2. However, once I close Visual Studio and reopen it (without rebooting the OS), the problem comes back immediately.
3. To fix it temporarily, I must sign out or restart the computer again.

Hypothesis: It seems like a background task, service, or debugger process is not closing correctly when Visual Studio exits, causing a conflict when I try to launch it again.

Request: Since a clean reinstall did not fix this, I suspect a system-level conflict or a lingering service.

1. Are there specific background services (e.g., vsjitdebugger, msvsmon) I should check?
2. Where can I find detailed logs to identify which component is hanging? I am willing to provide logs if needed.

Any assistance would be greatly appreciated as this blocks my development workflow.Critical New Observation:
