It looks like QIIME 2 is having trouble finding your file: ezbiocloud_qiime_full.fasta.
First step is that we should make sure that your file exists and that it is located where you think it is:
> ls /mnt/c/samples/ezbiocloud_qiime_full.fasta
If your terminal is able to find your file in that location, it will simply echo back /mnt/c/samples/ezbiocloud_qiime_full.fasta, If it is unable to locate it, it will give you a message that there is no such file or directory. If it can't find it, you will have to figure out where it is:
> locate ezbiocloud_qiime_full.fasta
