The conda version rnasik=1.5.3 has a default dependency of fastqc=0.11.7.
I ran into hanging of fastqc for whole day with most of my fastq files, similar bugs was also reported.
I found the possible cause in that the fastqc conda version lacks dependency of openjdk.
When I install conda openjdk, it seems fixed the problem.
So I would suggest you update to fastqc=0.11.8 or add the dependency openjdk in case unaware users ran in to hang of fastqc for very long time.
Refer to the latest release of fastqc.
