Regarding the little guy in the picture, I can't help with that, but in the file at the link - "NCF Neutral Creatures", all textures open without errors. And the archer textures, if that's him
Maybe your DDS plugin has crashed or broken.
Recently I updated my programs for viewing and editing the dds format, maybe something will come in handy for you too:
For viewing images and the DDS format - Imagine_1.1.1_x64_Unicode.rar (except for new dds formats like <BS7> and the like).
For simple viewing and re-saving to other formats (including new DDS formats like <BS7>) - NVIDIA_Texture_Tools_Exporter_2021.1.1.exe (Works independently via an exe file (you don't have to install it, you can unpack it with 7Zip and use two files "FreeImage.dll and nvtt_export.exe")).
For Photoshop - NVIDIA_Texture_Tools_Exporter_for_Adobe_Photoshop_2021.1.1.exe (a plugin, also can be installed without, just unpack with 7Zip into the "Plug-ins" folder the file "nvtt_export.8bi", for example in - "C:\Program Files\Adobe\Adobe Photoshop 2020\Plug-ins").
