Solution
This concerns a bug number 2603685, which is specific to the Q1 and Q3 versions of LabVIEW 2023 and does not occur in other versions. As an alternative solution, you can save the project using a previous version of LabVIEW, then open it in the 2023 version. This approach ensures that the dependencies and Build Specifications child items remain intact when you open the project in the new version.
