Can you open a julia repl and type using Pkg; pkg"st IJulia" for me?

The output should look something like

julia> using Pkg; pkg"st IJulia"
Status `~/.julia/environments/v1.5/Project.toml`
  [7073ff75] IJulia v1.21.3 ⚲

Also, could you show versioninfo()? For me, this looks like

julia> versioninfo()
Julia Version 1.5.3
