💻 Code

const option2 = 'option2';
const option3 = 'option3' as const;

export enum TestEnum {
  Option1 = 'option1',
  Option2 = option2, // <<< no errors here
  Option3 = option3, // <<< ts(18033) error here
}

🙁 Actual behavior

Blocked by ts(18033) error

🙂 Expected behavior

No ts(18033) error

Additional information about the issue

When string variable created as const it's impossible to use it as an enum value because of ts(18033) error.
As far as I'm aware this behaviour should've been implemented as part of this issue #40793
