"""
Based on the error log, this issue appears to occur because the 3DBX file does not include DEF information, leaving the design without die area (or floorplan) data, and the GUI crashes when it attempts to access this missing information.
Expected Behavior
Various features should be fully usable in the OpenROAD GUI when working with 3DBX. (without DEF files?)
Environment
OS: Rocky Linux 8.1
