So I did some research and it’s not actually freezing the editor, looks like dialog window size is busted.
The issue is that the sync dialog is modal, and the X button doesn’t work, so I can’t access any buttons to handle the closing of the window/editor for me.
I think it’s somewhat related I’ve noticed that on Linux editor outline and properties panels are moved all the way to the right.
I’ve also tried on Ubuntu 18.04 on a different machine and got the same results. I created an empty new project on the dashboard and tried to sync and got the same result.
On Windows, it works as intended.
