Segmentation Fault in libUSVWind.so Shared Library

[triakshunn]

Describe the bug
A segmentation fault occurs when running the simulation with the libUSVWind.so shared library. The error seems to originate from the WindObj::WindObj(WindObj const&) method, which is the copy constructor of the WindObj class.

Expected behavior
The simulation should run without encountering a segmentation fault.

To Reproduce
List the steps to reproduce the problem:

1. Run ros2 launch vrx_gz competition.launch.py world:=sydney_regatta
2. See error
