`using Plots` errors (`ERROR: LoadError: InitError: UndefVarError: `GR_jll` not defined`)

Here’s the timeline (time are EDT):

The issue was identified and a workaround became available in 2.5 hours. By my estimate there was a 4 - 5 hour window where this issue could have been encountered. It unfortunately corresponded with the 1.10.3 release when many people were also updating.

I think there might be some room for some CI improvements, and perhaps some extra special attention for Plots.jl. That said I’m overall impressed with the response.

Perhaps my only suggestion is to raise an issue earlier rather than later.
