Hi, I am Van. I'll be glad to assist you today.
Please try using a different browser to see if you experience the same issue. Additionally, if you have a VPN active on your device or any ad-blocking extensions enabled in your browser, kindly disable them before downloading the file.
If the issue persists, as an alternative, you can download the ISO using the Media Creation Tool. Download and run the tool, then click Accept on the license terms. In the next option, select the "Create installation media (USB flash drive, DVD or ISO file) for another PC" then click Next. In the "Select language, architecture, and edition" section, uncheck the "Use the recommended options for this PC" option, and then click Next. In the "Choose which media to use" section, select the ISO file, then click "Next". Choose the location where to save the ISO, then click Save. Wait for the process to finish downloading the ISO file.
Please let me know if you need any further assistance. I will be glad to assist.
