I was able to work around the problem by reverting changes to the closure versions in package.json

-    "google-closure-compiler-java": "^20220301.0.0",
-    "google-closure-deps": "https://gitpkg.now.sh/google/closure-library/closure-deps?d7736da6",

fix(hls): Fix type error in lazy-loading (#4687)

There was a potential type error in an edge case in lib/player.js. It
would have been caught by the latest compiler, so this upgrades the
compiler and fixes another type error in one other place, as well.
