compiling issues for package relying on rstan, compile_dll() aborts

[JoshSchramm94]

I am building a package relying on rstan (package can be accessed here). Recently, when running [devtools::do](pkgbuild::compile_dll()) as specified here my models start to compile again. I am getting tons of warnings regarding, for example
AppData/Local/R/win-library/4.5/RcppParallel/include" -D_REENTRANT -DSTAN_THREADS -O2 -Wall -gdwarf-2 -mfpmath=sse -msse2 -mstackrealign -UNDEBUG -Wall -pedantic -g -O0 -fdiagnostics-color=always -UNDEBUG -Wall -pedantic -g -O0 -fdiagnostics-color=always -c RcppExports.cpp -o RcppExports.o In file included from C:/Users/AppData/Local/R/win-library/4.5/RcppEigen/include/Eigen/Core:205, from C:/Users/AppData/Local/R/win-library/4.5/RcppEigen/include/Eigen/Dense:1, from C:/Users/AppData/Local/R/win-library/4.5/RcppEigen/include/RcppEigenForward.h:28, from C:/Users/AppData/Local/R/win-library/4.5/RcppEigen/include/RcppEigen.h:25, from RcppExports.cpp:4:
The documentation is aborted and I also can no longer install the package. I was not facing this issue before and also not on other devices. I have looked through the stan forum and have not found a solution for this issue.
I am using R version 4,5.3 and rstan version 2.36.0.9000.
