There are two likely causes of these errors:
The WorkSet.cfg does not contain the necessary variables, this can happen if a MicroStation WorkSet.cfg has been used as the source, in which case a whole series of dataset related variables will not be defined at the WorkSet level.
It is particularly important that the variable TF_DATASETNAME=Dataset_XX is defined in the cfg file of every workset. Please compare your own WorkSet.cfg with the example delivered with your regional dataset, for example: "C:\ProgramData\Bentley\AECOsim CONNECT Edition\Configuration\WorkSpaces\AECOsimExamples\worksets\BuildingTemplate_NM.cfg"
Another potential cause is that the necessary folders are missing from the WorkSet Standards folder.
The "Setting file has been modified by another user..." message shown above indicates that AnnotationOverrides.xml cannot be accessed. This can be resolved by basing your WorkSet contents on your regional dataset's example, e.g. BuildingTemplate_NM.
