Cursor Not Scaling on AI Boot Despite Correct User Interface Preferences

I'm having a strange issue where I unchecked the "Scale cursor proportionately" in the User Interface preferences but every time I boot up Illustrator, the cursor is huge again despite that setting being saved correctly.

If I open the preferences up at boot, the "Scale cursor proportionately" remains unchecked and I have to click ok for the cursor to reset back to the normal size like I want it. So at the moment, the only fix is to open and close the user interface every time I launch Illustrator.

Just trying my luck to see if anyone knows of a permanent solution. If not, it's okay. Not the end of the world.

P.S. I'm using the latest version of AI on Windows.
