log stops at " Init: Selected second frame, triangulated initial map."

[xji-apex]

I Initial first frame and then the rest of the algorithm seems to be working fine in RVIZ, but the log stops at " Init: Selected second frame, triangulated initial map."
No matter how far my camera moves，the log stops at Initial second frame. SVO runs with melodic.
I tried to run without BA or modified the parameters such as kfselect_mindist . but it doesn't work.....

Can anyone help me？Thanks a ton！！！
