This method worked for me. Run PowerShell and run the command to open the profile in your text editor:
notepad $PROFILE
In the profile file that opens, add this text from a new line
# >>> conda initialize >>> # !! Contents within this block are managed by 'conda init' !! (& "C:\Users\ivans\anaconda3\shell\condabin\conda-hook.ps1") | Out-Null # <<< conda initialize <<<
Save the file and restart the terminal
