Publishing fails: "Unable to compiling environment"

Hey guys, out of the blue I'm having trouble publishing as well as running my project. I keep get an error saying: Failed to publish: unable to compiling environment. When I try to run my agent is says: could not compile your agent, please try again later. (See screenshots)

I've done a hard refresh, tried creating a minimal copy with just the start step, etc but it's not working?

Please advise on what I can do or how I can fix it? We're in production already
