You can try a manual uninstall. It may be a time-consuming process, though. See https://support.microsoft.com/en-us/office/manually-uninstall-office-4e2904ea-25c8-4544-99ee-17696bb3027b.
Before you reinstall Office, run the System File Checker. For more information, have a look at https://support.microsoft.com/en-us/windows/using-system-file-checker-in-windows-365e0031-36b1-6031-f804-8fd86e0ef4ca.
