Hi @Juneyoung_Lee, welcome to :qiime2:!
In order to install and run conda & QIIME on an M1 mac you need to select the Terminal application, then press Command-I, to bring up the Terminal application information window. Check the box "Open using Rosetta". Then close / restart the Terminal app if needed.
Then install the regular version of OS X conda, not the M1 version. then everything should work as expected. At least this is all I needed to do to get it working on my laptop.
