Here are a few suggestions maybe can help to resolve the issue:

1. Start Excel in Safe Mode: Launch Excel in safe mode to disable any add-ins or customizations that might be causing conflicts. To do this, press and hold the "Ctrl" key while opening Excel. If Excel runs smoothly in safe mode, it indicates that an add-in or customization is likely causing the problem.
2. Disable Hardware Graphics Acceleration: Sometimes, hardware graphics acceleration can conflict with Excel and cause freezing. You can disable this feature by going to the "File" tab in Excel, selecting "Options," choosing "Advanced," and then under the "Display" section, checking the box for "Disable hardware graphics acceleration." Click "OK" to save the changes and restart Excel.
3. Check for Updates: Ensure that both Windows 10 and Office 365 are fully up-to-date. Sometimes, outdated software versions can lead to compatibility issues and performance problems. Install any pending updates and restart your computer.
4. Repair Office Installation: In addition to running the repair function, you can try a full repair of your Office installation. Go to the Control Panel, select "Programs and Features" (or "Add or Remove Programs"), locate Microsoft Office in the list of installed programs, and choose "Repair" or "Change" to initiate the repair process.
5. Disable Add-ins: Even if the Com Add-ins section appears empty, there might be other types of add-ins enabled. In Excel, go to the "File" tab, select "Options," choose "Add-ins," and under "Manage," select "COM Add-ins." Uncheck any add-ins listed and click "OK." Restart Excel and check if the issue persists.
6. Check Event Viewer: Open the Event Viewer on your computer (search for "Event Viewer" in the Windows Start menu), go to "Windows Logs," and select "Application." Look for any errors or warnings related to Excel in the log. The information might provide insights into the cause of the problem.
7. Create a New User Profile: Sometimes, user profile corruption can lead to Excel freezing issues. Create a new user profile on your computer, log in with that profile, and see if Excel functions correctly. If it does, you may need to migrate your data and settings to the new profile or fix the existing one.
