Communication Studio crashes when an invalid file path is entered during "New Solution" creation

Communication Studio crashes instead of validating the file path entered in the "Location" field when creating a new solution. The application should prevent invalid paths from being accepted, but instead it crashes.

Steps to Reproduce:

1.  1. Start Communication Studio
2.  2. Create a "New Solution"
3.  3. Enter a path with invalid characters into the "Location" field, e.g.:
4.  C:\Users\YourName\Documents\CommunicationStudio//......fahsdöfhaölksdhföalkishdföliahsdölkjhf-+-+#
5.  4. Press "Ok"

  
Expected Behavior: The "Ok" button should be disabled or show a validation error, because the path contains invalid characters.
 
 Actual Behavior: Communication Studio crashes.
