Dreamweaver loses ftp user namepassword - have to constantly re-enter both

On a random basis, Dreamweaver CC 2022 loses the server FTP user name and password. One day, I can upload files with no problem. The nextr day, I recive an eror message that an FTP caonnection cannot be made. I go to Manage Sites, click edit on the site, click servers, select a server ad click edit to find the username and password I set are blank. The FTP Address and Port still diplay, along with all the other information. Only the username and pasword are blank. I have to re-ente the username and pasword, test the connection and save the new information. I can then put files.

I can go for weeks without having this problem. Then, it will occure again.

Here are the specifications for version, OS and hardware.
