FLUX Schnell always gets stuck on the Sampler

[mikwee]

Hello,
I'm using the GGUF version of FLUX, since my Radeon RX 6600 has limited VRAM. No matter what workflow I use (and I've tried multiple), ComfyUI remains stuck on KSampler indefinitely. This is my current workflow, as taken from the WIKI Manual. The terminal output is stuck like this:

To disable this warning, you can either:
        - Avoid using `tokenizers` before the fork if possible
        - Explicitly set the environment variable TOKENIZERS_PARALLELISM=(true | false)

I used git pull. so I think I'm on the latest version. I'm using Fedora Linux. Hopefully this is enough information, tell me if you need more. I'd love help, so thank you.

I'm having the same issue. System RAM and VRAM aren't being maxed out at all. Sometimes ksampler gets stuck while loading, other times it works fine.
