Unable to install CA cert for local development on Windows 10 with VSCode

Expected behavior

Developer documentation https://docs.microsoft.com/en-us/office/dev/add-ins/quickstarts/outlook-quickstart?tabs=yeomangenerator works as expected

Current behavior

When running the dev server OR when trying to manually install the dev CA cert, I get the following:

The developer certificates have been generated in C:\Users\Nathan.office-addin-dev-certs Installing CA certificate “Developer CA for Microsoft Office Add-ins”… Error: Unable to install the CA certificate.

The larger output when running the dev server (vs directly installing the CA cert) is:

C:\Users\Nathan\source\ask\Ask>npm run dev-server

office-addin-taskpane-js@0.0.1 dev-server C:\Users\Nathan\source\ask\Ask webpack-dev-server --mode development

Steps to Reproduce

Smallest repro I could do is:

1. npm install -g yo generator-office
2. yo office
3. Select outlook as the project
4. npm run dev-server OR npx office-addin-dev-certs install
