Initially I have some problems with the program. Corel suggested to reinstall it witch I did. Now I can't even launch the program.
It's not Microsoft software. You should ask Corel about issues with their software.

Hello dears,
Still waiting for Microsoft to fix things so the software works properly again.

After spending an entire day researching this and working with various AI systems here is what finally worked for me: renaming the uvDV.dll file in the Video Studio program directory. According to Gemini, "(This disables a legacy DV capture module that frequently causes startup threads to hang indefinitely on modern systems)." Launching consistently now.

Boa tarde. Com sua sugestão o aplicativo Video Studio 2023 abre, mas alem de não salvar nada não desliga passado alguns instantes depois
This helps launch the software, but then it crashes when you play a project.

@Steven Tiberius you are quite wonderful. I have been going all over trying to resolve this ... repaired the installation, uninstalled and reinstalled, ran the complete 'Corel super-clean tool', further install, repair, nothing would work ... until this oh so simple fix. Thank you so much.
It would have been nice if Windows search could have managed to find the file in the directory rather than saying there was no such file, but it was there, and a rename and I'm back running again.
Thank you again @Steven Tiberius
Oh... @Mohammad AL Najjar is sadly spot-on. I can load and play one of the two sample clips, but any of my projects indead just case VS to exit a few seconds after trying to play anything...
Here is a Temporary Workaround from Corel:
VideoStudio 2023 Startup Failure on Windows 11 After Late August–Early September 2026 Updates
Hope it helps for now, and waiting for Microsoft to fix things.
This workaround (rename uvDV.dll to get VS23 to start, rename back to keep it working) is as per my post yesterday which came from work done with Corel L2 support and running numerous tests for them.
2026-09 Preview Update (KB5124010) is downloading as I type and so I'll report back on whether that resolves my issue and avoids the need for the 'double renaming' workaround. Thanks for posting the new Corel KB article, which strangely, they haven't mentioned despite the back and forth of requested testing and results and observations
2026-09 Preview Update (KB5124010) now installed and the issue remains...
I note the KB article does say the "update that may resolve the VideoStudio startup issue on some affected systems". Sadly, mine is not one of the resolved systems, but it's another data point to share with Corel L2 support so a worthwhile test. Thanks for the heads up @Mohammad AL Najjar
Worth adding that the 'Rename uvDV.dll and start VS23, rename back and continuing using VS23' trick continues to work. This allows VS23 to be loaded and then used and at least isn't too onerous.
Just a note to say a move to Win11 26H2 has not changed anything. Same behaviour as before
Okay, I appear to have a workaround:
Of note, my system doesn't and didn't have KB5120998 and yet I hit the VS23 load issue. The system also isn't running KB5124008 or KB5124010 so by my experience, these aren't involved in this issue
Today, we got this update.
Still, it didn't fix our problem; the issue is persistent.
Microsoft, PLEASE HELP!
My projects and work have been broken for over two weeks!
I presume this links to 'rumours' of KB5120998 being the issue and a fix via KB5124008?
My system is not running any of these, i.e. KB5120998 , KB5124008 or KB5124010. Updates jump from KB5120708 / KB5121003 / KB5126106.
VS2023 isn't running hence why I'm here
