For some weird reason, hitting Enter, Escape, or some other action keys crash the save dialog, open dialog, Command+F, and many others. This makes the entire app crash, and revert to an autosave which is likely very outdated (if at all).
This is after upgrading from El Capitan.
I can confirm clicking the Open, Save, Cancel etc buttons with the mouse work fine, but when I use the keyboard, the entire app crashes.
How do I fix this?
Edit: The following list will be updated with all solutions I have tried, and have failed:
Edit 2: I have confirmed this issue also applies to authentication dialogs and the like.
Edit 3: Somehow it got fixed. I don't know how or what caused it, but it just was. If anybody can educate me on this and tell me how this could have happened, please do.
Edit 4: The issue popped up again. I have no idea why.
