crashes with karras and dpm++ 2m (for me all john666 models)

currently i can use all john666 with only normal euler cause with karras it crashes on laststep-1

i'm using this code:

pipeline.scheduler = DPMSolverMultistepScheduler.from_config(
pipeline.scheduler.config,
algorithm_type="dpmsolver++",
use_karras_sigmas=True,
solver_order=2,
lower_order_final=True
)

ok, putting use_karras_sigmas=False seems to solve, thank you for your time.and sorry for the new message in another thread, i wasn't seen this.

Hmm, I think it's definitely a bug.πŸ˜…
If possible, please let me know which version of Diffusers you are using.
I'll check it out when I have some free time.
