r - Printing plots from list returns quosure error

Question

I have generated a series of plots using ggplot and lapply, like so:

makeplot <- function(data){

    require(ggplot2)
    require(dplyr)

    ggplot(data,aes(x=num,y=cat3, fill=cat3)) +
    facet_wrap(~cat2)
    # etc...
}

plot_list <- lapply(split(data, interaction(data[,c("province","cat1")]), drop = TRUE), makeplot)

I am using a large data frame that could be simplified to:

data <- data.frame(
    province = sample(c("1","2","3","4")),
    cat1 = sample(c("health","education","banks","etc")),
    cat2 = sample(c("winter","spring","summer","fall")),
    cat3 = sample(c("1 hour","2 hours","4 hours","8 hours")),
    Y = sample(1:100))

This generates a list of plots like so:

Plot list

I am attempting to print or ggsave out this list, as per here: Saving plots within lapply.

However, all attempts to export/print the resulting plots, whether with an lapply loop or a simple print statement return the following error.

lapply(plot_list,print)

Error: `quo` must be a quosure
Call `rlang::last_error()` to see a backtrace

I'm afraid the R documentation on quosures didn't yield any helpful insights. I'm not a developer and don't really understand most of the documentation. Can anyone help me out?

I originally posted this without much of the complex lapply filtering happening earlier, as it seemed a distracting irrelevance. I'm providing that now in case it's helpful. For reference, the actual data frame head looks like:
