ts-essentials: Compile error in 9.1.0

Upgrading ts-essentials from 9.0.0 to 9.1.0 causes a compile error in my project (but not on any of my own sources):

It’s a yarn 3.1.0 project (pnp enabled) with ts 4.5.4. My intellij doesn’t show any issue in this file. Not sure anything else could be relevant. Full source and build
