Database initialization does not occur, tables are not created or updated, and node registration fails.

Replacing only the updated DLL with the previous version immediately restores normal SQL connectivity and Pull Server operation. This strongly indicates that the issue is introduced by the newer DLL and occurs before the SQL connection stage.

The recommended next step is to open a Microsoft support case and include the Windows Server build, installed KB, both DLL versions, and relevant DSC, IIS, and Application logs. The older DLL can be used as a temporary workaround.
