RStudio crashing with convertFormat - Anndata to Seurat

I am working on a remote server and activated a conda environment : scRNAsaran. I am running the convertFormat command shown below and it will run for 15 minutes before my Rstudio session crashes unexpectedly so I am unsure of what is happening. My session info is posted below. Any suggestions?

ibrary(anndata)
library(reticulate)
library(sceasy)
loompy <- reticulate::import('loompy')
use_condaenv('scRNAsaran')

ad <- read_h5ad("./t-cells.h5ad")
sceasy::convertFormat("./t-cells.h5ad", from="anndata", to="seurat",
                      outFile='./tcells.rds')
