If there’s something I can do to try to further narrow this down, let me know
No problem; like I said, using node 20 works fine. I only noticed this issue recently, when I rebuilt my build environment, and tried doing so by the book (i.e. according to the docs).
If there’s something I can do to try to further narrow this down, let me know. I’m doing the build in an Ubuntu 24.04 VM, which I can restore to a working snapshot if testing causes it to break.
