It spat out 3000 lines of stuff. I can't make much sense of it except for the last line

I already saw that one, it doesn't mean anything, it means "access denied to memory", so try looking at the line above

or watch it in visual mode of depends ... like shown in one of the links, the errorings shows up in read, so look at last one, look above ...

I should note that if I move the open out of the sub, it works.

That would make me assume the encoding modules/files weren't packed completely or the wrong one is picked up or something else entirely ...

The next steps are exactly the same as I outlined in my previous linksss
