Configuration

module.exports = {

        '@babel/preset-typescript',
        [
            '@babel/env',
            {
                modules: false,
                useBuiltIns: false
            }
        ]
    ],
    plugins: [
        [
            '@babel/transform-runtime',
            {
                corejs: false,
                regenerator: false
            }
        ],
        [
            '@babel/plugin-proposal-decorators',
            {
                version: '2023-11'
            }
        ],
    ]
};

Current and expected behavior

If a function with a class instance as its type is specified as an argument for the property decorator, an error occurs when bundling the inherited class.
typescript eslint seems to handle properly. (no red line)
