tofbx.exe does not output any fbx file.

I am going to import FFXIV character's animation into blender using BlendrAssist, when I select the proper PAP and SKLB file and click the Import button, blender reports some errors that the file "import.fbx" does not existed. I have read the code that raise the exception, it seems that something is wrong when calling "tofbx.exe".
So I open the "tmp" folder in addons root folder, and there are "import_anim.hkx" and "import_skl.hkx" created by BlenderAssist. I manually run the "tofbx.exe" program, but nothing happend either, even if I turn on the compatibility mode or run as administrator.

The output of the terminal(the two hkx files are already copied to the bin folder):

PS C:\Users\Administrator\AppData\Roaming\Blender Foundation\Blender\3.4\scripts\addons\BlenderAssistAddon\bin> ./tofbx.exe -hk_skeleton .\import_skl.hkx -hk_anim .\import_anim.hkx -fbx .\out.fbx
HAVOK SKELETON FILEPATH IS: .\import_skl.hkx
HAVOK ANIMATION FILEPATH IS: .\import_anim.hkx
FBX FILEPATH IS: .\out.fbx

I am experiencing exactly the same - I tried with older versions of the addon, no luck either.
