Works for me on linux.

Thank you. Which Linux distro are you using? Feel free to send me a message directly. Thank you!

Nothing in error console.

Thank you. Which Linux distro are you using?

I'm using Ubuntu 23.04.

While researching this, I learned that Fn + F12 opens the context menu in macOS. It may be that Shift + F10 is not compatible with macOS.

By default, macOS doesn't allow opening the context menu with keyboard. You need to change your accessibility settings. This discussion shows how to update your settings: https://apple.stackexchange.com/a/101300.
