'Excel asks to save even though I did just save

I've uploaded a video on Youtube showing the problem (Youtube because I can't do it on StackOverflow directly).

Any idea why I have this problem? I'm using Microsoft® Excel® for Microsoft 365 MSO (Version 2203 Build 16.0.15028.20178) 64-bit for enterprise on Windows 11.

My add-ins: enter image description here

Here is a link to download the file.

EDITs: Safe Mode fixes the problem. De-activating my (only) add-in fixes the problem. Still not satisfied because I want to use Excel with the add-in and I don't want to launch it in safe mode everytime.

EDIT2: On my other laptop which also works on Windows 11, I do not have this problem.
