How to fix 4k video downloader not working on Windows 11?

[Windows Server]

Hello everyone!

I'm new to this and recently tried to download an online video, but the 4K Video Downloader recommended by the search engine doesn't work at all on my computer. Whether it's installing or clicking the download button, the software interface flashes back or is unresponsive. My system is Windows 11 24H2 with the latest graphics drivers and Python environment installed. Anyone with similar experience? Or know of any alternative tools to recommend if 4k video downloader not working?

Problem details and solutions tried.

1. The software says “Unable to resolve video URL” or “Network connection failed”, but the web video plays normally;
2. Browser ad blocker is turned off, try another browser (Chrome/Firefox);
3. Reinstall the software and check “Disable all plug-ins”, but the problem persists;
4. Checked the system log and found the error code: XXX (if I remember).

Is it possible that the site's anti-downloading mechanism is causing the problem? Or does it require a specific configuration? I'm asking for your guidance!
