I ran into the same issue yesterday and today when trying to update WooCommerce on a locally installed site. Windows Defender prevents the file from being accessed and moves it to quarantine, and Chrome refuses to download it from the plugin site.
However, I have updated version 7.6.0 for other sites in the same local environment about a week ago, and I haven’t had a similar issue before. I’m able to copy and package the WooCommerce 7.6.0 version that was installed last week. I can also download any other older or newer version from the plugin site, but currently I’m unable to download the 7.6.0 version.
