qsiprep QSIprep recon_only is stuck at "plot

When I ran the following QSIprep code, time qsiprep-docker /scratch/connectome/dyhan316/dwMRI/UKB_sample/sub_02_INPUT_4/ /scratch/connectome/dyhan316/dwMRI/time_it/outputs/recon_variety/multi_msmt_noACT/ participant --output_resolution 1.2 --recon_only --recon_input /scratch/connectome/dyhan316/dwMRI/UKB_sample/sub_02_INPUT_4/ --recon_spec mrtrix_multishell_msmt_noACT --fs-license-file /scratch/connectome/dyhan316/dwMRI/license.txt --skip_bids_validation --nthreads 48 --omp_nthreads 24 --stop_on_first_crash to only do reconstruction using data that was already preprocessed, I got stuck at the following step:
