After installing DESeq2 on a computing cluster in a user's account, (using the command "conda install -c bioconda bioconductor-deseq2"), I tried to check on it to make sure it had installed properly, but received the following error (please see bottom):

I am using R 3.6.1, and have also tried the method shown on this website: https://bioconductor.org/packages/release/bioc/html/DESeq2.html

please advise.

Generally, if you're trying to use bioconda then all packages should be installed using bioconda. I'd try to isolate the problem by verify / correcting the installation of stringi (via conda), which is being reported as the package that cannot be loaded.
