"Connect to AWS" error: unable to get local issuer certificate

**Describe the bug**

Error suggesting invalid profile on machine with existing credentials file in use with aws cli

**To Reproduce**

After installing and ctrl+shift+p -> connect to AWS on a machine that already has a credentials file in the home directory, the user is given a list of profiles in the credentials file. Selecting either of my profiles returns an error "Credentials profile is invalid"

**Expected behavior**

AWS connects to that profile.

I read through https://github.com/aws/aws-toolkit-vscode/issues/705 which shows the same symptoms but following the recommended steps of reinstalling the latest VSCode, restarting it and having lower case credential key names didn't work for me.

Here is the content of my credential file with altered keys:

```
[default]
aws_access_key_id = BKDLSKEJFLKASKJFKELS
aws_secret_access_key = adklsfjASDfksa2+akdzADSFwekfasdfjslkedsf
[sand]
aws_access_key_id = BKDLSKEJFLKASKJFKELS
aws_secret_access_key = adklsfjASDfksa2+akdzADSFwekfasdfjslkedsf
[dev]
aws_access_key_id = SKDASDLFKJSKSKJFKELT
aws_secret_access_key = fasdfjslkedadklsfjASDfksa2+akdzADSFweksf
```

Please let me know if you have any suggestions.

Thank you!

Start from the Ctrl+Shift+P “Connect to AWS” entry point and reproduce the failure on Windows with an existing credentials file and multiple profiles. Compare the extension’s behavior with the working AWS CLI commands; done means selecting either profile connects without the invalid-profile or certificate error.
