Vegas Pro broken since 2026-04 Security Update (KB5083769) (26200.8246) Cannot Render Unless I reboot

Tnap_tf2 20

After I did this months update Tuesday, my copy of Vegas 22 Pro automatically freezes when I click render. It doesn't matter what encoder I use (MainconceptAVC or my NVEC Codec), what format I choose (MP4 or MP3), or even the resolution (I swap between 720p and 1080p depending on the video project. Only after rebooting the entire PC does it let me render ONCE, then it no longer let's me render files.

I also have up to date GPU Drivers, have cleared my Vegas' cache, and reinstalled the program itself, to no avail.

Multiple people online have stated it's being caused by this latest windows update

Does Windows acknowledge this issue and are they going to be pushing a fix for it? As it was caused by their update.

My Specs are

Win 11 Home

Ryzen 7 9700X

32GB DDR5 6000MT/s RAM

RTX 5060 ti 16GB GPU

NVME SSD

Hi, good day!

I recommend reporting the issue via Feedback Hub app to notify Microsoft.

https://support.microsoft.com/windows/send-feedback-to-microsoft-with-the-feedback-hub-app-f59187f8-8739-22d6-ba93-f66612949332

Please try to uninstall the KB5083769 update.

https://support.microsoft.com/windows/how-to-uninstall-a-windows-update-c77b8f9b-e4dc-4e9f-a803-fdec12e59fb0

If this fixes the issue, please try to temporarily pause updates to prevent it from reinstalling.

Open Settings > Windows Update > Pause updates > Pause for 1 week

I look forward to your update and am happy to continue working with you until the issue is resolved. If you find the answer helpful, please click "Accept Answer" and consider upvoting it. Otherwise, please keep me posted by clicking "Add comment" below instead of selecting Yes or No.

I did just that, uninstalled both updates from the 14th, and posted in the feedback hub

Thanks for the update, that’s a good step. Uninstalling the recent updates helps rule out a bad install and logging it in the Feedback Hub is definitely the right move so Microsoft can track it.

Hopefully this gets picked up and addressed in a coming patch. In the meantime, it’s worth keeping an eye on Windows Update in case a new cumulative update rolls out a fix.

Alright, I also prompted others to report it, as it's been happening to various versions of Vegas Pro, from 19 to 23. And with it being so expensive, it's hard to justify upgrading to hope it fixes the issue.

I will say, until this is fixed I cannot update windows at all, and I do want to update to ensure my security is garenteed, but I can't if this prevents Vegas from working

Same issue. Very similar system configuration to Tnap_tf2. Vegas 23. Uninstalling KB5083769 fixed it. Reported the problem to MS using feedback hub. Agree that it's concerning to have to pause updates, so I hope there is a prompt resolution.
