KIndly help, I am not able to solve my problem, I will be highly thankful

You would have to tell us what software interface you are using. This help forum is for people using R and Bioconductor packages directly. You seem to be using a non-Bioconductor interface to limma because the messages you show are not from limma or voom. You are obviously using the limma and edgeR packages but via some interface or script, and the error is coming from the interface.

I guess you are probably using the Galaxy interface, but there is no way for us to help you with that. You would need to contact the Galaxy help forums.
