So close, but I need an expert eye

Okay I figured it out!
After doing some digging, I found that there are restrictions on querying the “collections” field in “Stores/Products”. The basic idea is that you can only search for the collections if you know the _id field.

I have tested the below code on my site and it returns the correct number for each collection. Replace your current function with the async function below.

async function getFrozenCounts() {
    var frozenCollection = (
        await wixData.query('Stores/Collections') 
        // Get the collection from the Wix Collections database
        .eq("name", "Frozen")
        .find()
    ).items[0]

    wixData.query("Stores/Products") // Wix Stores database
        .include("collections")
        .hasSome("collections", frozenCollection._id)
        .count()
        .then((num) => {
            let count = num;
            if (num > 0) {
                // If there ARE frozen dishes
                $w("#frozenNumber").text = "There are " + count + " frozen dishes available to order"; 
                console.log("Number of Items = " + count)
            } else {
                // If there are NO frozen dishes
                $w("#frozenNumber").text = noFrozenText;
                console.log("None = " + count)
            }
        })
}
