Question: Fixing a corrupt maple file (Maple 2022)

I have some lecture notes and examples that suddenly appears to be corrupted. I am getting the following error code when trying to open the file: "There was a problem in the loading process, you worksheet may be incomplete."

I've tried the following trouvleshooting:

- Close and reopen Maple

- Restarting computer

- Tried different computer

note: I have no backup files as I do not have autosave switched on.

I have also tried looking into the solution posted on a previous question on this site (https://www.mapleprimes.com/questions/235363-How-To-Fix-Corrupted-Maple-File), i.e.  changing the file format to.xml and making changes but with no luck :(

Is anyone able to help me fix it and un-corrupt this file:

Lecture_2_-_notes.mw
