By the url you shared in the question, it seems the host of the meeting is using Zoom's Cloud Recordings tool. It allows the sharing of the file to other people, but the owner can block downloads (specifying it on the Viewers can download settings). If you believe you should have access to the file, I advise you to get in contact with the host that recorded and shared the video - he might change that settings or just send you the file some other way. However, as I mentioned before, some companies does that (block downloads) to avoid information leakage.
