- Observed behavior

Report the Copy and Paste Defect to Microsoft
Since this specific freezing issue is identified as a potential software defect, reporting it directly to Microsoft with detailed information is the most effective way to help them issue a permanent fix.
Because community forums cannot directly fix underlying software bugs, providing Microsoft's engineering team with precise details about your crash helps them investigate and patch the defect in future updates.
Open Microsoft Excel (after restarting from the freeze) and click on the 'Help' tab located on the top ribbon menu.
Click on the 'Feedback' button in the toolbar and select the 'Report a Problem' option from the dropdown menu.
In the description box, include your exact Excel version, details about the workbook (size, formulas, formatting), the specific steps you took before the freeze, and how frequently the issue occurs.
Check the options to include diagnostic data, attach a screenshot or screen recording of the error if you captured one, and click 'Submit' to send your report.

Clear the Office Clipboard
Clearing the clipboard history can temporarily resolve sudden unresponsiveness if overloaded memory during copy and paste operations is contributing to the freeze.

Frequently Asked Questions
Why does my Excel freeze every time I copy and paste?
Excel may freeze during copy and paste due to known software defects, conflicts with third-party COM add-ins, an overloaded clipboard, or excessive conditional formatting applied across the workbook.
Will I lose my data if Excel freezes during a paste operation?
If the worksheet becomes completely unresponsive and requires a forced restart, any unsaved progress may be lost. However, you can often recover your work using the Document Recovery pane when you reopen Excel.
Can a large amount of copied data cause Excel to crash?
Yes, copying and pasting massive amounts of data—especially cells containing complex arrays, formulas, or rich formatting—can exceed your system's memory limits and cause Excel to become unresponsive.
How do I find my Excel version to include in the bug report?
Open Excel, click on 'File', then select 'Account' (or 'Help' in older versions). Your full version and build number will be clearly displayed under the Product Information section.
