I tried rolling back to 2.8.3 of parcel, which some reports suggested avoided this issue, but got stuck in a catch-22 where some things where complaining they needed 2.9.3 which is the one with the bug.
Seems like it'll solve itself eventually, but thought I'd note it.
I was getting an error when running yarn build.
Similar to this report: https://github.com/parcel-bundler/parcel/issues/9174
Googling around this seems to be due to a dependency of parsel and the fix is due out soon.
