Try removing this round bracket..highlighted in Red..

Code:
awk -F: '!/^#/ && !Done{$2="Changed_Pattern");Done++}1' OFS=":" file

Corrected one..

Code:
awk -F: '!/^#/ && !Done{$2="Changed_Pattern";Done++}1' OFS=":" file

Rats - overlooked that right parenthesis when adapting earlier proposal. Yes, just remove it.
