Error "no supported WSMan client library was found." with macOS pwsh

From macOS Terminal, when I execute:

pwsh -command "Enter-PSSession myhost"

I get error from PowerShell:

Enter-PSSession: This parameter set requires WSMan, and no supported WSMan client
library was found. WSMan is either not installed or unavailable for this system.

I've spent 2 hours to find a solution. I am going to answer my own question.

Root cause of the issue is Powershell dependency to previous openssl version. It is apparently not easy to fix according to GitHub issue PowerShell/#5561.

Here is the workaround I have found:

curl -L https://github.com/tebelorg/Tump/releases/download/v1.0.0/openssl.rb \
  -o openssl.rb
brew install ./openssl.rb
