Thanks for bringing that to my attention, it was a typo in the altrep materialization logic (from my other package). Can you try the fix below?

devtools::install_github("traversc/stringfish@59eff5449b7cd1981f73db47f758a56a24aa4f57")
install.packages("qs")

library(palmerpenguins)
library(qs)
library(tidyverse)
species <- c("Adelie", "Gentoo", "Chinstrap")
data <- lapply(species, function(x) penguins[penguins$species == x, ])
data[[1]] # good
data[[1]][, "bill_length_mm"] # good
file <- tempfile()
qsave(data, file)
without_altrep <- qread(file, use_alt_rep = FALSE)
without_altrep[[1]] # good
without_altrep[[1]][, "bill_length_mm"] # good
with_altrep <- qread(file, use_alt_rep = TRUE)
with_altrep[[1]] # good
with_altrep[[1]][, "bill_length_mm"] # Should work now
