Unable to import Markdown file.

Problem to Solve

I am migrating back to OneNote from Obsidian and I clipped a page with Obsidian's Clipper and I wanted to import that to OneNote. All it has is a youtube embed and a callout with the description from YT.

EDIT: Seems like simple files with just text in them are failing due to the names being wrong. I removed all spaces, underscores, or anything. There are just letters and numbers now with no spaces and it is still failing for Message: Illegal characters in path.

To Reproduce

Download this note.
attempt to import
get error

Expected Behavior

For it to at least import all of the text as a header

Screenshots

File I am importing: Harvard_CS50s_Artificial_Intelligence.md

Screenshot of that note:

Environment (if applicable)

• OneNote Version: Latest version
• OneMore Version Latest version - just updated prior to posting this BR.
