Issue while exporting with xplane2blender 4.2.0 version

Hey there, I am getting the following issue while trying to export objects from blender. I have never ever seen this issue arise before, this is happening the very first time for some reason :
Python: Traceback (most recent call last):
File "C:\Users\sh_ar\AppData\Roaming\Blender Foundation\Blender\4.2\scripts\addons\io_xplane2blender\xplane_ops.py", line 586, in execute

ret = _op_call(self.idname_py(), kw)
