Unable to Open or Delete a Folder

Hello. I am attempting to open a folder and nothing is happening when I attempt to open it. If I attempt to delete it, the attached error message is generated. This is for this workflow: https://civitai.com/models/790080/inpainting-simple-workflow-flux-or-upscale-or-lora-or-gguf. The workflow is also generating errors as if I don't have the flux 1-dev-q8_0.gguf file, but I'm not sure if I do, since I can't access the folder in question. Any tips? Thank you!
