I ran conda uninstall in the Anaconda Prompt to uninstall a package in my base environment. During the uninstall process, it also uninstalled packages needed by Anaconda Navigator (64-bit). So Anaconda Navigator seems to be deleted from Windows’ Start Menu.
Fortunately, most files are still in C:\programdata\anaconda3\ and I can use the Anaconda Prompt. I also still have my environments. How should I repair Navigator without deleting my environments? Thanks.
