Hello Huan Nguyen,
Thanks for reaching out today.
I am sorry but I am unable to see what that image says, please could you let me know as I would love to look further into this for you. In the meantime, please can you try the following steps and let me know how you get on?
It would also be beneficial to know which region you are in, as currently not all regions support Google Assistant.
I look forward to your response.
