cleanup

(1) the package is failing on r-devel-windows-...-UCRT because lots of
packages are missing on that platform (rms, ggplot2, Hmisc, testthat)

(2) the noLD platform is listed under "additional issues"; when I look
at the logfile I see one place where a .Rout and a .Rout.save file are
off by a few least-significant digits, and one place in a test where an
additional warning is thrown during the testing process.

Start with the r-devel-windows UCRT and noLD check logfiles mentioned in the issue. Inspect the .Rout and .Rout.save comparison and the test that emits an additional warning, then determine which missing packages or platform-specific differences must be addressed. Done means the affected checks no longer report these failures.
