Hello Boongsongum, welcome to the Microsoft community.
Based on your feedback, you are having issues with Messenger.
Are you referring to the old version of Messenger or the chat function in Settings > Personalization > Taskbar?
Currently, the old version of Messenger no longer has technical support.
You can try using new software as an alternative, such as Skype, personal Teams, and other software.
Hope the above information is helpful to you.
