This appears to be a regression in newer versions of UiPath.UIAutomation.Activities, where the SAP Logon Path parameter is ignored and the activity defaults to saplogon.exe.
You can try the following workarounds:
Downgrade the package to version 25.10.21 (recommended, as it works correctly)
Use saplogon.exe instead of saplgpad.exe in the SAP Logon Path
Launch SAP manually using a Start Process activity before executing the SAP Login activity
Please mark this as a solution if it works for you.
