AppleScript Error - Syntax Error

I have Keyboard Maestro macros that call AppleScripts to open FileMaker Pro and open a specific file. This AppleScripts have worked for years but since the update to MacOS 12.5 from 12.4 they stoped working. I am now getting the error:

Expected end of line but found """.

The script is:

tell application "FileMaker Pro"
getURL "fmp://server/File.fmp12"
end tell

When running this in Script Editor, after clicking OK in the error dialog, it highlights the " just in front of fmp:. Any clues what is different now?
