Hello **Michael Slifkin,**Following up on your issue, if the application is suddenly failing to initialize, hanging on the splash screen, or crashing unexpectedly, the most statistically probable cause is a corrupted global macro template or a malformed registry configuration rather than a strict licensing lockout.
To immediately isolate the fault and restore functionality, ensure all Office executable processes are terminated, then navigate to the %appdata%\Microsoft\Templates directory using the Windows Run dialog. Locate the Normal.dotm file and rename it to Normal.old, which safely forces the application to build a pristine, default template structure upon its next execution. Should the unhandled exceptions or hangs persist after this file regeneration, you must clear the application's volatile registry state. Launch regedit.exe and navigate directly to the HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Word\Data path. Deleting this specific Data subkey strips away corrupted UI customizations and forces Word to initialize with factory-default parameters, resolving the vast majority of sudden operational failures without impacting your stored documents. Once you restore application stability using these methods, you can securely navigate to the File and Account interface to verify your cached identity or deploy the official Microsoft Support and Recovery Assistant (SaRA) utility from the Microsoft Download Center to safely diagnose and automate the resolution of any lingering subscription token mismatches.
