Dependency package "package_name" not available

Question

I'm getting a strange error when trying to build and reload in RStudio. In my description file I've included a package that I have built and maintain within my organization. It's not on CRAN. Essentially, when I update the DESCRIPTION file (Depends: ...), I get this error:

==> devtools::document(roclets=c('rd', 'collate', 'namespace', 'vignette'))

Updating fczstudy documentation
Loading fczstudy
Error in (function (dep_name, dep_ver = NA, dep_compare = NA)  : 
  Dependency package surv3 not available.
Calls: suppressPackageStartupMessages ... <Anonymous> -> load_all -> load_depends -> mapply -> <Anonymous>
Execution halted

In this case, surv3 is a package that I maintain within my organization - I can confirm that it is indeed installed because I'm using it.

This doesn't seem to happen with other packages from CRAN. It just started a few days ago. It's not allowing me to import my package (surv3)

I'm really not sure how to debug this.

traceback() in the console after ctrl+shift+B returns nothing

Unselecting the circled option in Project Options > Build Tools dialogue solves this problem, although I'm not quite clear on why:
