MacOS Sequoia, Excel for Mac, Crashes when applying conditional formatting using the formatting pane. I attached the crash report.

There's no "com.microsoft.Excel" files in the Library folder (the MS provided solution is to delete them and restart). Does this mean the only solution is to reinstall Office?

    Thank you for reaching out and sharing your issue in the Q&A forum. Based on the details you provided and the steps you’ve taken, I tested the same scenario in my environment using macOS and an equivalent version of Excel. The results indicate that I was unable to reproduce the crash you experienced.

    Given this, the most appropriate next step is to check your Office version and consider rolling back to a previously stable build. The process depends on how Office was installed:

    -If installed from the Mac App Store: You cannot roll back to a previous version. Your only option is to uninstall the App Store version and reinstall Office by downloading it from the Microsoft website: Download, install, or reinstall Microsoft 365 or Office 2024 on a PC or Mac

    -If installed from the Microsoft Website (Retail/Web Download): You can roll back by:

    • Uninstalling your current version of Office.
    • Visiting the Update history for Office for Mac page and downloading the installer package for a stable older version (e.g., 16.100 or 16.99).

    After updating or rolling back, to prevent automatic updates:

    • Go to Word >> Help >> Check for Updates
    • Uncheck Automatically download and install
