Search the PDF’s raw stream for /F1Normal. If you see /F1Normal.0 or /F1Normal+0, you need to map both. In your cidfmap, add:
/F1Normal.0 /LiberationSans ;
/F1Normal+0 /LiberationSans ;

For batch processing multiple problematic PDFs, use the open-source Ghostscript tool:
gswin64c -dNOPAUSE -dBATCH -sDEVICE=pdfwrite \
-sOutputFile=output.pdf input.pdf \
-c "/CIDFont findresource dup /F1Normal known pop pop /F1Normal /Courier-CID def ifelse" -f
This command tells Ghostscript to intercept any call for F1Normal and redirect it to a valid CID font (Courier-CID). Some PDFs have font substitution disabled by the creator
