Conda not activated in Power Shell

Question

I have already install anaconda on my Windows 10 laptop. I'm trying to activate the Python environment named pyenv.

First, I check the conda env list in my laptop, this is the output on the power shell:

PS C:\Users\User> conda env list
# conda environments:
#
base                  *  C:\Users\User\Anaconda3
pyenv                    C:\Users\User\Anaconda3\envs\pyenv

Then I activate pyenv:

PS C:\Users\User> conda activate pyenv

But I check again, it still activates base environment:

PS C:\Users\User> conda env list
# conda environments:
#
base                  *  C:\Users\User\Anaconda3
pyenv                    C:\Users\User\Anaconda3\envs\pyenv

When I use the Anaconda prompt, it works normally:

(base) C:\Users\User>conda activate pyenv

(pyenv) C:\Users\User>

Does anyone know why it causes this problem and how to fix this?

Update:

Running conda init powershell:

PS C:\Users\User> conda init powershell

Update 2: It works when using CMD:

C:\Users\User>conda activate pyenv

(pyenv) C:\Users\User>

Answer 1

After a while, my Powershell appear this error when I open it.

. : File C:\Users\User\Documents\WindowsPowerShell\profile.ps1 cannot be loaded because running scripts is
    disabled on this system. For more information, see about_Execution_Policies at
    https:/go.microsoft.com/fwlink/?LinkID=135170.
    At line:1 char:3
    + . 'C:\Users\BinoyGhosh\Documents\WindowsPowerShell\profile.ps1'
    +   ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
        + CategoryInfo          : SecurityError: (:) [], PSSecurityException
        + FullyQualifiedErrorId : UnauthorizedAccess

Then I found this solution.

• Run Powershell as Administrator
• Run this line set-executionpolicy remotesigned
• Close the terminal

Then it works.
