Dear Uswr-limons162,

This is a known issue due to a recent update. See article Description of the security update for Excel 2016: September 08, 2026 (KB5002914)

The only workaround at the moment is to roll back to a previous version using this command:

Please type cmd in the search on the taskbar. Don't press enter key yet. Instead, choose "Run as administrator" to launch Command Prompt.

For Office 2019:

"C:\Program Files\Common Files\Microsoft Shared\ClickToRun\OfficeC2RClient.exe" /update user updatetoversion=16.0.10417.20197

See here for the history office's version, so check this blog post of Gunter Standard.
