After Hours, simply installing the latest Visual C++ Redistributable V14 (both x86 and x64) was the fix.

There is no need to uninstall anything beforehand. Just run:

vc_redist.x86.exe

vc_redist.x64.exe

from the latest V14 version available here: https://learn.microsoft.com/cpp/windows/latest-supported-vc-redist?view=msvc-170#latest-supported-redistributable-version

I was able to repair the vc_redist.x86.exe, but the vc_redist.x64.exe was missing completely. After installing it, everything suddenly works again!

This helped me. Christmas was the only time it worked. Then, it just kept crashing every time I tried opening the program. I even ended up going from Sony Vegas Pro 18 to Pro 23 thinking that it was just my computer not liking Pro 18 or my Arc B580. Well, Then, I went and tried running it with the RTX 5070TI and same thing. I tried the whole update drivers and even downloaded the ntdll.ll. Nothing worked. Once I ran the VC rRedist, boom. Sony vegas is back baby. Thank you so much.

Did you try to update your graphic drivers to the last version?

I checked and they're on the latest, apparently I have a windows update though so I'm gonna try that and see what happens. I've also already tried sfc /scannow and reinstalling vegas to no avail.

The error you are encountering with Sony Vegas related to ntdll.dll and the unmanaged exception (0xc0000005) can be indicative of several underlying issues. Here are some steps you can take to troubleshoot this problem:

Check for Windows Updates: Ensure that your Windows operating system is fully updated. Sometimes, updates can resolve compatibility issues with applications.
Run System File Checker: Use the System File Checker tool to repair missing or corrupted system files. You can do this by running the command sfc /scannow in an elevated Command Prompt.
Check for Disk Errors: Run the Check Disk utility to confirm there are no file system errors. You can do this by right-clicking the drive in File Explorer, selecting Properties, then Tools, and clicking on Check.
Check for Sufficient Disk Space: Ensure that you have enough free space on your hard drive, as insufficient space can cause applications to malfunction.
Reinstall Visual C++ Redistributables: Since you mentioned reinstalling Visual C++, ensure that you have the correct versions installed that are compatible with Sony Vegas.
Run in Safe Mode: Try running Sony Vegas in Safe Mode to see if the issue persists. This can help determine if third-party applications or services are causing the conflict.
Contact Support: If the problem persists after trying the above steps, consider reaching out to Sony Vegas support for further assistance, as they may have specific solutions for issues related to their software.

These steps should help you in diagnosing and potentially resolving the issue with Sony Vegas not starting due to the ntdll.dll error.
