Unzip cannot unzip fastqsanger.gz file and no error reason is displayed

This is a screenshot of the file not decompressed, and the reason for the error is not shown.
What I unzipped is a fastqsanger.gz file,which was processed after Trimmomatic. The size of the compressed file is 2.1GB. After the operation, it is displayed in red, and the error reason is not displayed. What is the problem? Is there a size limit for the unzip module input file?

Hi @siqiyu,
