Please refer to the attached screenshot and let me know if anyone can help me out.
The error in your screenshot about the input to fastqc not being in gzip format may hint at corruption of your uploaded fastq data, which can be seen from time to time with transfer of large datasets over the internet. In this case reuploading the data is likely to fix the issue.
Alternatively you might have set fastq.gz as the datatype manually when the data is actually uncompressed.
