Since I upgraded to Monterey (from Mojave), I cannot run anymore a local server that was installed under /Applications.

The app has no extension, the file type is "Unix Executable File". It was working perfectly before the update.

Now when I try to run it from shell it fails with

> -bash: ./ManicTimeServer: `cannot execute binary file`

What's going on? Why the app doesn't run anymore?

And, mainly, **how do I make it run again?**
