I use julia v1.3.0 and have trouble saving a few variables in a .jld file. I get the following error

First thing I would check is whether you have permissions to create/overwrite `/home/nv/Downloads/MC/1.jld`.

I did, and I have access. I tried saving on a MacOS as well as Windows. I get the same error in both places. As suggested in an earlier post, I tried reinstalling HDF5 using home-brew and then did a `build HDF5` in Julia. But, nothing seems to be working.
