mise activate pwsh | Out-String | Invoke-Expression invalid operation

[robertwt7]

hi Everyone

I've decided to install Mise on my windows PC, quite excited because i've been using WSL to use asdf

However when I'm following the docs to install using winget, the last step to activate the shell fails

what i'm doing is simply mise activate pwsh | Out-String | Invoke-Expression

the result is:

PS C:\Users\rober> mise activate pwsh | Out-String | Invoke-Expression
PS C:\Users\rober> mise
InvalidOperation:
