Can you please be more specific? Does X2Go Client itself quit unexpectedly? Does
the client itself work, but does starting a session not work? When does what
exactly quit?

I know that the client often crashes when starting it for the first time on
macOS. I tried debugging this years ago but never managed to find the root
cause. It's also not easily reproducible, since subsequent launches don't crash.

That mostly sounds okay - you may be seeing random VRAM content instead of the
nxagent/x2go logos within the nxproxy window, which is a bug, but also a
difficult one to reproduce. It doesn't actually cause any problems, neither,
since the image will be updated later on by a window manager or the like.

We don't provide official builds for 10.14 as of now... but I highly suspect
that even a client build targeting 10.14 wouldn't change the situation.

Sounds like the session startup itself doesn't work correctly when called from
the macOS client, but it's difficult to tell what exactly is happening.

18.04, I figure?

The image was not attached correctly, only the file name made it into the
message as plain text.

Nothing interesting in here. Looks all normal so far.
