Comment 3 for bug 1962734

If the Screen class makes problems, then there must be messages or exceptions. Make sure they are visible.

--- When I remove just the Screen class ...
Removing the class means, that no SikuliX features are run, that might crash.

Most probably in your TeamCity environment there is no accessible real screen or at least a fake screen, that is accepted as non-headless.
SikuliX needs access to a real screen.
If the Screen class is initialised in a screenless environment, an exception is thrown and no features work.
