After some checking, the error is caused by sending a null string to TMP_InputField

public void TMProInputFieldValueChanged(string value)
        {
            if (!SetValueOnEndEdit)
            {
                //1.This line set Text.Value to null
                Text.Value = TextMeshProInputFieldComponent.text;
            }

            TMProUpdatePlaceholder();
            ValueChanged.Trigger();
        }

    public override void TextChanged()
    {
            if (OnlyTriggerValueChangedFromUI)
            {
                TextMeshProInputFieldComponent.onValueChanged.RemoveAllListeners();
            }
            //2.Text.Value is null caused the error
            TextMeshProInputFieldComponent.text = Text ?? String.Empty;

            if (OnlyTriggerValueChangedFromUI)
            {
                TextMeshProInputFieldComponent.onValueChanged.AddListener(TMProInputFieldValueChanged);
                TMProUpdatePlaceholder();
            }
}

There's no error when removing ContentType field of input field in xml.
