deblur taking forever?

I am trying to use deblur as a denoising package

My dada2 code is which worked well, when I instead of deblur.

and my deblur one is
qiime deblur denoise-16S
--i-demultiplexed-seqs single-end-demux-filtered.qza
--p-trim-length 250
--o-representative-sequences rep-seqs-deblur.qza
--o-table table-deblur.qza
--o-stats deblur-stats.qza

the deblur is working forever until the terminal is deactivate on its own.
I am qiime2.2021.11 in Ubuntu 20.04.3 LTS (GNU/Linux 5.11.0-34-generic x86_64)
