DADA2 Help with "dada2 denoise-paired"

Hi @PengGongxin,
Welcome to the forum!

Thanks for providing the full error message + qiime2 version, in the future please make sure to additionally provide us with the exact commands you've also used for troubleshooting purposes.
I believe the key error is this:

names’ attribute [84] must be the same length as the vector [82]

This is similar to this post here, which had set --p-n-threads to 0 for automatic detection over a cluster which had led to some incorrect thread calculations. Manually setting this value to the desired number of cores to use should solve the problem. Could you give that a try and let us know how that goes.
Good luck!
