Wan2GP gives "Requires Flash-Attention version >=2.7.1,<=2.7.4 but got 2.8.3."

What happened?

I installed Wan2GP, and got the following error: "Requires Flash-Attention version >=2.7.1,<=2.7.4 but got 2.8.3."

I tried using the Python version override to override flash-attn to 2.7.3, but this didn't do anything.

I am on Arch Linux and installed through the AUR.
