Offending Command: ashow
This error can be caused by text that has been offset (e.g. kerning has been used, the document contains super- or subscripted text or custom letter- or word spacing).
Check all text in the job for any of the above characteristics.
An Ashow error may also point to a damaged font so you could also try updating those.
Kerning: Kerning refers to the horizontal space between individual pairs of letters (a kerning pair). Fonts that are properly kerned appear evenly spaced without large open gaps of white space between characters.
