Rcpp package error for RShiny app republication

Question

I'm having issues re-publishing an RShiny app I have published (and re-published) previously.

The app runs fine locally (in the RStudio preview and if I run it in my browser), but when I try to re-publish it, I get this error and the re-publication process aborts.

make: *** [/opt/R/4.4.2/lib/R/etc/Makeconf:204: barrier.o] Error 1
ERROR: compilation failed for package ‘Rcpp’
* removing ‘/usr/lib/R/Rcpp’## End Task Log ################################################################
Error: Unhandled Exception: child_task=1510757110 child_task_status=failed: Error building image: Error building Rcpp (1.0.13). Build exited with non-zero status: 1
Execution halted

Here is a notepad file with the entire deployment process output incase there is something useful there that I don't know about.

I initially thought it was a one-off issue, but I've tried re-publishing the app over the past two months now and I keep getting the same error.

The GitHub linked on the app has a lot of files, but the actual app code is this file.

I tried re-reunning the app, waiting to see if this issue would be fixes on Shiny's end, and checking that my Rcpp package is up to date

See https://forum.posit.co/t/error-building-rcpp-1-0-13-when-deploying-shiny-app/196970 There was a problem in v1.0.13 of Rcpp, but it has been fixed and the newer version is now on CRAN. So if you run install.packages("Rcpp") and retry, it should go smoothly.
