Error in image preprocessing. Auto focal point crop is not work.

[724791ce]

The following error statement appears and the task crashes when auto-crap is applied.
All works well if auto crop is disabled.

I found the following interesting statement regarding this issue.
AUTOMATIC1111/stable-diffusion-webui#11727
This is the same problem as the above page, and I wonder if this is due to the open cv version upgrade (4.7 series→4.8 series) that came with the control net update.
I have a log of open cv 4.8 in my PC that was upgraded on the day the problem occurred.
But i dont know how to downgrade.

AUTOMATIC1111/stable-diffusion-webui#11727 (comment) worked?

[724791ce]

I did it.
I tried the link procedure.
Downgrading opencv from 4.8 to 4.7.0.72 in the venv used in webui. After that, everything worked out fine.
Now that the issue is resolved, I'll close this place.
