I have globally installed Typescript version 3.7.3 and Visual Studio Code is using the same version, yet I am unable to access functionality specific to Typescript 3+. For example, when trying to declare a variable with the type "unknown", I encounter a compile error stating: "Cannot find name 'unknown'." However, it does appear as a suggestion in IntelliSense. How can I troubleshoot this issue?
