It's not Microsoft software. You should ask Corel about issues with their software.

Hello Rudolf Beim,

Welcome to Microsoft Q&A forum.

If the issue come directly from the app malfunctioning, then you should contact the app developer about the issue with their software.

However, I'd like to make sure what exactly cause the app to not open. Before we proceed further, can you tell me how to apps behave when you try to open it? Additionally, can you please go to Event Viewer > Application to see if the system register log about the apps being opened?

I'm waiting for your reply.

Hello Rudolf Beim,

Thanks for replying.

I'll see what I can do. I'll keep you updated.

Answer 2

I followed these instructions below, which I got from Chrome's AI search. This fixed the Video Studio problem for me, for now at least.

Option 3: Use the Windows Recovery Environment (WinRE)

Sometimes Windows prevents uninstallation because the update files are currently active and locked by the operating system.

Hold down the Shift key while clicking Restart in your Windows Start Menu. This boots you into the blue Advanced Startup screen.
Go to Troubleshoot > Advanced Options > Uninstall Updates.
Choose Uninstall latest quality update. If it fails or still blocks you, select Command Prompt from that same Advanced Options menu.
In the command prompt, type wusa /uninstall /kb:5120998 and press Enter to see if the standalone installer tool can remove it outside the main OS window.

Prevent it from Reinstalling

Once you successfully remove the update, you must block Windows from immediately downloading it again:

Go to Settings > Windows Update.
Turn OFF the toggle that says "Get the latest updates as soon as they're available". This stops optional, unstable "Preview" updates from forcing themselves onto your PC.
You can also click Pause updates for 1 week to give Microsoft time to patch the bug before your system scans for updates again. [1, 2, 3]

--In my case I paused updates for 3 weeks. Hopefully Microsoft fixes the issue by the time this update reinstalls.
