Answer 1

to rephrase the solution I did to solve such issue, I believe one of the 2 reasons below will cause such issue.

Broken/ incomplete downloaded zips This may have occurred because you cancelled or closed the VS out of frustration because it was taking too much time.

while in fact the visual studio is downloading the zips at AppData/Local/Xamarin/zips. because you closed visual studio, the zip files are not completely downloaded.

what you do is go to AppData/Local/Xamarin/zips delete all the zip files then AppData/Local/Xamarin you should only see Universal, zips and logs folders delete the rest. wait for the zips to install completely. this is gonna take time for sure.

Problem with the References Check if any of the references are showing any warning sign or something. if so remove the reference and reinstall it.
