Yes, the error occurs at the Beginning of the Broden step 1 (after Broyden step 0), before the iter step 1.
About the iprcel, I have just test it again and didn't see the error.

Leave diecut at its default value and try again: 0.5Ha seems very small. Or try without iprcel, to see if that is where the bug comes from.

As usual, we could help more efficiently with full information on the platform and a bit more of the output/log.  Did this occur at the begining of a second Broyden step? What do you mean "had error with the (iprcel etc) lines"?

I have tried ABINIT 5.6.4 but abinis also had error because of these lines in the input file:
iprcel 45

This is the input file:
