Yes. Something strange is happening on macOS 10.13. I'm still looking for the problem (and solution) but thus far haven't found it.
Marked is not sold in the App Store, so it's not required to follow the same security rules. My suspicion is that's where the problem is occurring, which also explains why Marked continues to work in 10.13
