Конда не установлена ​​PackageNotInstalledError: Пакет не установлен в префиксе

Question

Я новый пользователь Anaconda, и мой навигатор Anaconda не запускается каждый раз.Я пробовал другие ответы в сети, такие как установка PATH и «conda update --all» в Anaconda Prompt.Следующая ошибка возникает даже после того, как все сделано:

(base) C:\Users\utkar>conda update conda

PackageNotInstalledError: Package is not installed in prefix.
  prefix: C:\Anaconda3
  package name: conda

Прилагается отчет об ошибке, созданный conda:
