Since the update, I'm getting the following error when trying to export a model or an animation:

Python: Traceback (most recent call last):
File "[redacted]\AppData\Roaming\Blender Foundation\Blender\4.5\scripts\addons\io_scene_valvesource\export_smd.py", line 260, in execute
if bpy.app.debug_value <= 1: ops.ed.undo()
^^^^^^^^^^^^^
File "C:\Program Files\Blender Foundation\Blender 4.5\4.5\scripts\modules\bpy\ops.py", line 109, in __call__
ret = _op_call(self.idname_py(), kw)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
RuntimeError: Operator bpy.ops.ed.undo.poll() failed, context is incorrect

This occurs on Blender 4.5 and 4.5.2
