I thought this was just VP23 r278 but also now occurs in VP22 & VP21 which has never been the case. The program starts and gets to the "Creating windows" part then crashes out. I have sent Magix the crash dump but not heard anything back yet.

I have uninstalled & reinstalled VP23. Updated the NVIDIA drivers, run scansfc & DISM, cleared as many temp folders etc. I can find, reset the settings at startup, and now at a loss. I see others had this error many versions ago but nothing recently.

It sound to me like a faulty Windows file. The basic info returned is:
 

 Application Name:    VEGAS Pro
   Application Version: Version 23.0 (Build 278)
   Problem:             Unmanaged Exception (0xe0434352)

   Process Image Date:  2025-09-04 (Thu Sep 04) 16:43:08
 

The event viewer is showing this error every time the crash occurs.

The attempt to locate the Open procedure "OpenLsaPerformanceData" in DLL "C:\Windows\System32\Secur32.dll" for the "Lsa" service failed with Win32 error code The specified procedure could not be found.. Performance data for this service will not be available.

Any thoughts please as unable to edit anything?
