Dataflows Maximum Mashup Length Exceeded

Hello, while trying to add a dataset to a Power BI dataflow in the workspace (copying/pasting M code from a desktop file into a "blank query"), I get the error message shown in the image attached.

One such query was a simple set of M code to generate a last refresh date.

Has anyone seen this, or does anyone know how to get around the issue?  The error message might as well be heiroglyphics... no idea what the heck any of it is telling me to do.

Sample code shown here:

Spoiler
let
   Source = #table(type table[Last Refresh=datetime], {{DateTimeZone.FixedUtcNow() as datetimezone}}),
   #"Changed Type" = Table.TransformColumnTypes(Source,{{"Last Refresh", type text}})
in
   #"Changed Type"

Put simply, what is a mashup, why am I exceeding the maximum length, and how would I go about refreshing this mashup to continue?

Whenever I see mashup, all I think about is my sweet NKOTBSB album, but alas, expertly crafted transitions from "Backstreet's Back" to "Step by Step" aren't going to help me here.  There's no maximum length for a solid Backstreet Boys/New Kids on the Block mashup (and by golly there shouldn't be), so why is there one here?
