As far as I know, the referred problem was resolved shortly after that.
On my side, "rungs" in TeXLive 2019 does not cause such trouble, both on
windows 10 and freebsd 12.  I quote the partial log of the former below.

Maybe your rungs is confused by the two instances of the ghostscript
executables, namely the one under c:/texlive/2019/tlpkg/tlgs and
"mgs.exe".
