I am trying to use scDblFinder and while it worked with fewer cells (currently attempting with a SingleCellExperiment with 32682 rows and 238578 columns) now it is crashing the process. The problem seems to come from base R 4.4.0 with Bioconductor 3.19 trhough BiocParallel which I am using with MulticoreParam(workers = 10, progressbar = interactive()) (There are 24 CPUs in my machine).

sce2 <- scDblFinder(gex_filt,  
                     samples = "Sample", dbr = 0.08,
                     BPPARAM = MulticoreParam(workers = 10, progressbar = interactive()))
 saveRDS(sce2, here::here("data", "sce2.rds"))

This is the first report I could get, after running the application from the terminal via quarto render quarto/batch.qmd.

(electron) 'crashed event' is deprecated and will be removed. Please use 'render-process-gone event' instead.
