I had Vegas Pro 21 which worked fine but today it stopped working. I was on the edge regarding upgrading to Vegas 23 so I thought I should upgrade to Vegas Pro 23, unfortunately Vegas Pro 23 also gave me the same error. It crashes as soon as I start it and problem report shows this :-

Problem Description
   Application Name:    VEGAS Pro
   Application Version: Version 23.0 (Build 302)
   Problem:             Unmanaged Exception (0xc0000005)
   Fault Module:       C:\WINDOWS\SYSTEM32\ntdll.dll
   Fault Address:       0x00007FFA514BC1FE
   Fault Offset:         0x000000000001C1FE

Two probable cause that I can think of is that there was a recent windows security update and I updated my CCTV software Blue Iris from version 5 to version 6. Both of this should not cause an issue with Vegas but there hasn't been any other change in my system.

Before posting here I did a google search for troubleshooting and have tired the below mentioned things but it didn't help.

1. Restarted my PC.
2. Updated GPU driver to the latest version.
3. Ran it as administrator.
4. Used Control + Shift while starting the software.
5. Uninstalled and reinstalled Vegas 23.
6. Uninstalled and reinstalled Microsoft Visual C++ Redistributable v14.
7. In Vegas' installation folder renamed the subfolder named UPS to UPSold.
8. Looked to uninstall MS Visual Studio but it wasn't installed.

System details :-
Windows 11, Intel i7 14700k CPU, AMD 7900 XTX GPU, 128 GB Ram.

Please help.
