Problem running read.loom.matrices command

[CJ1017]

Hi, I'm having trouble reading in previously generated loom files. When I try to run read.loom.matrices() I keep getting the following error.
I have R 3.6.1, gcc 5.5.0, and have openmpi, hdf5, and boost installed.

Thanks.

loom<- read.loom.matrices(file) reading loom file via hdf5r...
