I'm runing HECV-SCM encoder with scc cfg file but it can't output IDR frame

Question

The version I used is HM-16.16+SCM-8.5 and use

./TAppEncoderStatic -c ../cfg/encoder_intra_main_scc.cfg -c ../cfg/per-sequence/Desktop_420.cfg  -i ../../yuv/bridge-close_qcif.yuv -b wstr.bin -o wrec.yuv -wdt 176 -hgt 144 --SummaryPicFilenameBase true --SummaryVerboseness true -f 60

the inputfile is yuv420P format、 8bit depth and resolution 176x144

the output message
