It looks like ChimeraX got far enough to start the user-interface event loop. Did you see the ChimeraX window at all, even briefly?

If you have used ChimeraX successfully before on this machine, it’s possible that the saved preferences/settings got corrupted. So if you have used it before try removing the C:\Users\<user-name>\AppData\Local\UCSF\ChimeraX\ folder and see if that makes a difference.
