Is this JuliaPro? If so, this looks similar to [Pkg problems - Impossible to update packages and to install some of them](https://discourse.julialang.org/t/pkg-problems-impossible-to-update-packages-and-to-install-some-of-them/11182) and [NullableArrays: resolve is unable to satisfy package requirements](https://discourse.julialang.org/t/nullablearrays-resolve-is-unable-to-satisfy-package-requirements/10891)

Can you try the regular command line Julia from [Download Julia](https://julialang.org/downloads/) ?
