如何修复将所有数据设置为相同的mutableMapOf

fun fixMutableMapOf(map: MutableMap<String, Any>): MutableMap<String, Any> {
    val fixedMap = mutableMapOf<String, Any>()

    for ((key, value) in map) {
        var isDuplicate = false

        for ((fixedKey, fixedValue) in fixedMap) {
            if (value == fixedValue) {
                isDuplicate = true
                break
            }
        }

        if (!isDuplicate) {
            fixedMap[key] = value
        }
    }

    return fixedMap
}
