Error occurs when I try to open project in Designer

Question

When I try to open a project from the menu [Open project] in Designer, I get the following error.
What is the cause and workaround?

System.ComponentModel.DataAnnotations.ValidationException: You cannot use the following characters. \ / : ; * ? ' " < > | ~

Answer

This error occurs when a project that can be viewed by the logged in user has a project name that contains restricted characters.

HULFT Square Designer restricts users from using the following characters.

-\ / : ; * ? ' " < > | ~
-Platform-dependent characters and end-user-defined characters

Therefore, please check each project name in the project list, and modify the project name if there is a project that contains any of the above restricted characters.

Please refer to the following manual for details on HULFT Square Designer specifications.
