Microsoft Excel 2021 Freezing - Microsoft told me to post here

Going along with my previous suggestion, if it works in Safe Mode, but doesn’t work when you restart normally, then it may be one of the system extensions you have installed causing the problem.

However, that problem would affect all users unless the particular System extension was not loaded for the other user.

Yes I did delete the container files. The same issue still occurs.

I understand. I was just pointing out that it would have to be something. Being sandboxed, all of that should be contained, but with Microsoft, I don’t know.

A safe mode restart might clear some caches that could possibly fix the problem.

While in safe mode, see if it works. It may be klunky, but not freeze up.

Restart normally after.

If it is a user account problem, I would first try deleting the sandbox Container for the app.

You can find it in your user Library/Containers folder.

To get to the user Library, hold down the Option key and select Library from the Go menu.

I don't know why Microsoft support doesn't know how to reset its applications.

Do you have the current release of Excel and Word (16.63.1)? Both are working fine for me on Monterey 12.5 on a 16-in MBP M1 Pro. Is the source of the documents you are attempting to open from Office on Windows, or documents exported from another non-Microsoft application?

Interesting Microsoft would send you here as they are responsibile for their applications working correctly on macOS.

We need to know more.

Please run Etrecheck and post its full report here. Use the "additional text" button and paste the report into the text box.

This will tell us about other software modifications that you have installed and could be affecting this.

Microsoft answered a few questions and since it only freezing under my user profile and not a guest profile they told me it wasn't an issue with their program :/

If it is only their app freezing, then the problem is in their app, or the user-specific configuration files it creates—that’s why I suggested deleting the sandbox, to reset user config files.

I don’t think it matters, whether you have a subscription or a single license, Microsoft makes you sign in to use the app.

Also, there are online collaboration features, and they would prefer you save the documents in their cloud.
