VSCode Make Apps SDK Invalid Token Error

Hello! Whenever I try to make a new environment (>Make Apps: Add SDK Environment) in the VSCode extension for make, I get this error:


(Your token was probably not valid or some error ocured. Please try again to start using Make Apps SDK.)

It’s important to note that I have been able to create multiple environments using 2 other accounts on this device. The account that is providing the API Key causing errors is newly created (as of ~3 days ago).
I have tried using a different PC with a different installation of VSCode, and still receive the same error.
I have also tried creating API keys with different permissions, and multiple brand new API tokens, and nothing seems to work.

Has anyone else faced this issue before? If not, just any information on what may be happening, and how to approach this issue, would be appreciated, thanks!
