Confirm the PC supports DirectX 12, repair Vanguard through Battle.net or Steam, and launch once with overlays and known conflicting utilities closed. When the main menu appears, stay there until Shader Preloading completes. A generic firewall bypass, Windows compatibility mode, or display-scaling change is not a supported black-screen fix.
Confirm the PC meets Vanguard's minimum requirements and has a DirectX 12-compatible system. Remove any old Windows 7 or 8 compatibility-mode setting from the game executable because those systems are not supported.

Repair Vanguard
In Battle.net, select Vanguard, open the gear menu, and choose Scan and Repair. In Steam, open Properties > Installed Files and choose Verify integrity of game files. Wait for the check to complete.
3
Launch without known conflicts
Close overlays, recorders, input remappers, and unneeded performance utilities for one launch. Activision specifically lists NZXT CAM, MSI Afterburner, and Razer Cortex as possible conflicts and advises updating Razer Synapse when installed.
4
Restore ASLR only if it was disabled
If you previously disabled Windows Address Space Layout Randomization, re-enable it before retesting. Leave the default Windows security settings unchanged if you never edited them.
5
Wait at the main menu
Launch Vanguard and stay at the main menu until Shader Preloading finishes. Activision warns that leaving the main menu stops this process and can cause performance problems.
6
Verify the startup result
Close and reopen Vanguard once with the same clean setup. The task is complete when the game reaches the main menu, renders normally, and completes shader preloading without returning to a black screen.
If it does not work
If a clean test works, re-enable optional overlays and utilities one at a time to identify the conflict.
If Vanguard remains black while other games also fail, troubleshoot the graphics driver, monitor connection, or Windows graphics stack before reinstalling Vanguard again.
If only Vanguard still fails after verification, perform Microsoft's clean boot as an isolation test and send Activision the exact failure time, PC specifications, launcher, and steps completed.

Activision's Vanguard PC guide supports the requirements, repair, application-conflict, clean-boot, ASLR, and shader-preloading sequence.
