Error occurred in typescript 4.7

[ChoSeoHwan]

I want to use this library,
but an error occurred when using it and I can't use it.

Environment

• node js : v16.13.0
• typescript : 4.7.4

My Test Code

import { Enum, EnumType } from 'ts-jenum';

@Enum<TestEnum>('code')
export class TestEnum extends EnumType<TestEnum>() {
    static ONE = new TestEnum(1);
    static TWO = new TestEnum(2);
    static THREE = new TestEnum(3);
    static FOUR = new TestEnum(4);

    private constructor(readonly code: number) {
        super();
    }
}

Error message

    static ONE = new TestEnum(1);                                                                                                          
                 ^
