I have noticed version 4.5.2 works, I will test each version to identify where it stopped working on Windows to narrow it down.
I will update this comment when I have found the culprit.

Version 4.5.3 crashes to desktop, every version afterwards will show a terminal window, but trying to navigate at all creates pointer errors and causes connection resets making the software unusable on windows as the host/server machine.
I haven't had a chance to test the other platform binaries to see if they also suffer from this issue.

Interesting. Thank you for reporting. I would first try to update the dependencies and rebuild it. I can make a pre-release to test.
