Error connecting to https://id.sc-mvp.localhost/.well-known/openid-configuration

I received the below error(s) when trying to start-up Sitecore MVP site in a brand-new machine (Windows 11). When I googled one of those, I couldn't find any results either:

The error(s) occurs whenever CM or id instance' entry is not present in hosts file. So, there are multiple types of errors presented to us as listed below. The simple solution is to:

Add the concerned entries to host file under C:\Windows\System32\drivers\etc:

127.0.0.1 id.sc-mvp.localhost

127.0.0.1 cm.sc-mvp.localhost

Error-1:
