Can't apply checkpoint model - missing DLL "bias_act_plugin"- module not found

[AlexxB31]

Hello, I can't add any checkpoint model.
An excerpt from the log message: window

...
File "", line 573, in module_from_spec
File "", line 1233, in create_module
File "", line 241, in _call_with_frames_removed
ImportError: DLL load failed while importing bias_act_plugin: Das angegebene Modul wurde nicht gefunden.
(Module not found).

In general I couldn't run DragGAN until now after many hours of installing all requirements.
Thanks for help
