"expected chunk" but actually "didn't expect \\n or maybe <"

Hello,

I'm being stubborn and trying to do things outside my experience level, so I apologize if this is a dumb noob error. I haven't even tried to debug it properly yet but I did manage to find the smoking gun or maybe the smoke-in-mirrors; I see what went wrong but not why and have no idea how to investigate. I attached the source file and parsed tree for reference. Thank you for your work with this; I should be able to continue working through the file now in any case!

I went to try to "walk the tree" and went down a bit of a rabbit hole not realizing that "Chunk" was not actually a Python thing at all before digging into the error...

chonker = open("rig","r")
text = str(chonker)
tree = ast.parse(text)
print(ast.to_pretty_str(tree))

my ultra basic debug output I stuck in places found this:

[@0,0:0='<',<35>,1:0]

the '<' looked out of place here, but wait, there's more...

"String": {
"s": "See the ShowDemoWindow() code in ReaImGui_Demo.lua. <- you are here!",
"delimiter": {},
"stop_char": 15553,

}

what I suspect could be the sneaky escape artist literally just a scroll away

"String": {
"s": "The \"Tools\" menu above gives access to: About Box, Style Editor,\\n",
