Additional Notes
This may be connected to the issue, so I’m just going to mention it for added context:
I’ve noticed that when pasting variables in the details panel, the field will play a highlight->fade animation for half a second. Now, if you paste a value to a second field before the first has finished animating, the first property will replay its highlight->fade animation along with the second property. If you repeat this action and paste a value to three fields in a row, getting them all highlighted at once, the editor will crash.
The fact the prior field animations are retriggering tells me something may possibly be awry. This does not occur if you’re copying in quick succession (via SHIFT+RMB). It only occurs when you’re pasting.
I first discovered this in 5.5.1 built from source. And have managed to reproduce it in 5.5.2 binary in a fresh project. Also, tested it with enums, array elements and integers.
