SB-KERNEL::ARG-COUNT-ERROR upon printing to stdout

Manjaro Linux
sbcl-bin 2.3.4
mondo 0.1.0
Swank bundled with Slime 2.27

Output of ros version:

roswell 22.12.14.113
build with gcc (GCC) 12.2.1 20230201
libcurl=8.0.1
Quicklisp=2021-02-13
Dist=2023-02-15
sbcl-bin-variant=''

I get the following error whenever I evaluate something that prints to stdout:

Mondo seems to otherwise be working fine; looking forward to getting to use it more.
