I am having this same issue with none of the suggestions fixing it. Error in storage.mode(x) <- "double" : 'list' object cannot be coerced to type 'double'

          @YitengDang Hi， may I know if you have solved your problem now?  I also met the same issue. 

1. future::plan("multiprocess", workers = 4)
   Error: ‘node$session_info$process$pid == pid’ is not TRUE

when I changed the code, it still appeared.

future::plan("multisession", workers = 4)
Error: ‘node$session_info$process$pid == pid’ is not TRUE

Interesting, only by this code it worked. And the following "identifyOverExpressedGenes" ran well.
future::plan("multisession", workers = 1)

But, if workers more than 1, error appeared again:

future::plan("multisession", workers = 2)
Error: ‘node$session_info$process$pid == pid’ is not TRUE
future::plan("multisession", workers = 3)
Error: ‘node$session_info$process$pid == pid’ is not TRUE
future::plan("multisession", workers = 4)
Error: ‘node$session_info$process$pid == pid’ is not TRUE

2. for netClustering(), I changed
   netClustering <- function(object, slot.name = "netP", type = c("functional","structural"), comparison = NULL, k = NULL, methods = "kmeans", do.plot = TRUE, fig.id = NULL, do.parallel = TRUE, nCores = 1, k.eigen = NULL)

but it reported:
Error in storage.mode(x) <- "double" :
'list' object cannot be coerced to type 'double'

when I modified "kmeans(data.frame(data.use),kRange[x],nstart=10)$cluster",
it showed "Error in as.data.frame.default(x[[i]], optional = TRUE, stringsAsFactors = stringsAsFactors) :
cannot coerce class ‘"umap"’ to a data.frame "

So, could you help me to solve these problems? Thank you very much!
