RSA Algorithm is depracted in latest versions of OpenSSH. To use Pubkeys with remote systems that haven't upgraded you need to add the two lines as shown below to hosts in your config.

Host *.ssh.wpengine.net
  HostkeyAlgorithms +ssh-rsa
  PubkeyAcceptedKeyTypes +ssh-rsa

This is my local dev stack for the Windows Subsystem for Linux (WSL2). The stack consists of NGiNX, PHP7.4-fpm, and MariaDB. Additional tools and setup include: wp-cli, nvm (node version manager), SSL Certificates, and WindowsTerminal

First, you need to get WSL2 installed and activated. See here.
