R session crash if plan is not changed back to sequential after using multisession (in linux) about future HOT 2 CLOSED

I don't have much knowledge in this area, but one thing you could try, both to narrow in on the root issue of the crash and as an alternative to "multisession" is to install the package "future.callr" and then use the following plan (instead of the "multisession" plan):

future::plan(future.callr::callr)

If you don't switch back to sequential at the end, do things still work well with the above plan?

Yes, using future.callr::callr as plan works as intended. R processes are spammed when computation begins, and closed afterwards, freeing the memory. Also, Rstudio doesn't crash when restarting/closing session without changing plan to sequential.

I can use this workaround for the moment for my own development, but I would like to know why is this happening with plans from future, as is the default recommendation in docs from furrr and other packages and probably the one that users of the package I'm developing will use.
Is there any more info I can provide to help narrowing the issue?
