AWS Connection not working anymore

[ruipinto-pleo]

Describe the bug
AWS Connection doesn't seem to be working with both JVM apps or the terminal.

To reproduce

1. "Open AWS Local terminal" via side bar, the resulting console is not authenticated

This used to work, now I have to login again whenever I open a console.

2. Adding a connection to Kotlin App doesn't trigger any AWS auth or provide credentials to it

This was working recently, I've tried to update IntelliJ to the latest version, still running into issues.

Expected behavior

When running an app or the terminal, the AWS connection should be provided automatically when setup, so the app/terminal can use it to interact with AWS resources.
