Installation fails in PowerShell

**1. Please specify the following:**
- OS: Windows 10 20H2
- Shell (Bash, PowerShell, Zsh, etc.): PowerShell 7

- [x] **I have reviewed the troubleshooting tips described [here](https://github.com/aws/aws-elastic-beanstalk-cli-setup#23-troubleshooting) and they do not solve my problem**

**2. Description**
I `git clone` and run the installer and get this error, but I have set the `Get-ExecutionPolicy` as described in the readme.

```
PS C:\Users\david> .\aws-elastic-beanstalk-cli-setup\scripts\bundled_installer

It would great if there was an `.exe` to install this.

Start with scripts/bundled_installer and scripts/install-python.ps1, then review the README troubleshooting section for the documented PowerShell execution-policy assumptions. Reproduce the Windows 10 and PowerShell 7 installation failure and determine whether the installer can run successfully under the reported policy settings; done means the installation completes without the shown script-loading errors.
