In the meantime, kindly try these steps:
1> Run Excel in Safe Mode
Close all Excel windows.
Press Windows key + R > run: excel /safe
Open a blank workbook and test copying several times.
If copying works in Safe Mode:
Open Excel normally.
Go to File > Options > Add-ins.
At the bottom, select COM Add-ins, then Go.
Record the enabled items, then clear all checkboxes.
Restart Excel and test.
Re-enable the add-ins individually until the issue returns.
Repeat with Excel Add-ins in the Manage list. Open Office apps in safe mode on a Windows PC | Microsoft Support
