EDIT: Oops, I see I mistakenly posted about the desktop version in an iOS thread. Apologies; I'll find a better place to move this.
I don't know whether this is the same as OP's issue, but I can reproduce some unresponsiveness pretty much 100% of the time with the following steps:
- Open a private window
- Switch to another application, and copy a URL from there via right-click
- Return to Orion.
The private window does not respond to the keyboard. I cannot paste, nor close the window from the keyboard, nor switch with Command-` Clicking in the address bar has no visible effect, although I can type into it - just not paste, and there is no cursor bar shown. Usually the unresponsiveness continues even if I close that window (using the menu bar) and open a new one. (Sometimes it affects other windows that were already open - including the missing cursor bar if there's a text field in that window.)

This is most reliably reproducible when copying a link from another Orion instance that is generated from "Install this site as an App", but it seems like it can happen with any source. I can't reproduce it in a new clean profile, but I can if I copy my default profile. However I have no plugins installed. Perhaps this has something to do with history? (Wild speculation.)
I know this is incomplete information; let me know what else I can provide that would be helpful.
