Shortcuts now requires shift after windows update

I’m using a Belgian AZERTY keyboard on Windows 11 with Microsoft 365 Excel. Until recently, I could trigger shortcuts such as “Increase Decimal” command using the Ribbon access key sequence Alt → H → 0 by pressing the unshifted “à” key.

After the latest Windows update, Excel only recognizes the digit 0 if I press Shift + à during the sequence. This breaks my workflow because I don’t have a numpad and my Quick Access Toolbar is already optimized for other commands.

Question: Is there a Windows or Office setting that changed how Ribbon access keys interpret digits on AZERTY keyboards? How can I restore the old behavior so the unshifted “à” key acts as 0 in Ribbon sequences?
