Thanks for reporting the issue. Unfortunately I can not reproduce it on 
any of my systems here.



I also tried on a "clean" Debian stable install with:



   docker run -it --rm debian:bullseye bash

   apt update && apt install yarnpkg

   yarnpkg --version



and I get:



   1.22.10



I run the command under strace and it looks like indeed it does not find 
/usr/share/nodejs/yarn/node_modules/@babel/runtime/helpers/interopRequireWildcard.js, 
but it then proceeds to also try 
/usr/lib/x86_64-linux-gnu/nodejs/@babel/runtime/helpers/interopRequireWildcard.js 
(not here) and finally 
/usr/share/nodejs/@babel/runtime/helpers/interopRequireWildcard.js (this 
one is there).



With:



   dpkg -S 
/usr/share/nodejs/@babel/runtime/helpers/interopRequireWildcard.js



I find that interopRequireWildcard.js is installed by package 
node-babel7-runtime which is listed as a "dep" of yarnpkg here:

https://packages.debian.org/bullseye/yarnpkg



Is it possible that on your system you have installed some non-Debian 
node module that takes precedence over the ones installed by the Debian 
packages?
