What’s interesting is that we can see that main editor application becomes “out of focus” after you open the UI Toolkit Editor Window tool. So the application seems to be actually giving the focus to that new window, but it is nowhere to be seen.
Are you in a multiple-monitor setup? It would be worth trying in a new project if you can reproduce the same issue as well.
If nothing works, I would recommend filing a bug report (Help > Report a Bug…).
That’s it! I keeṗ forgetting that this lappy has a totally pointless second screen.
Thanks.
I deleted all my layouts and reinstalled the IDE trying to figure out what was going on.
