Loading packages fails when is not possible to change directories

[llrs-roche]

Somehow the package fails to change directory even if cd works on windows:

library("multiloadr")
# add packages to multiloadr
add_pkgs("teal.reporter", "teal.reporter")
add_pkgs("teal.widgets", "teal.widgets")
add_pkgs("teal", "teal")

# load packages from presently active branch
load_pkgs(branch_name = c("teal_reportable", "main"))
## Error in system2("cd", args = c(path, "&& git branch"), stdout = TRUE) : 
##   '"cd"' not found
traceback()
