I’ve found something, it seems to be related to me having two inspector windows open at the same time. I think this is a reasonably common unity workflow as you can lock one inspector which is useful for copying/contrasting component data.
The Open Typescript button seems to only render in the older of the two inspector windows, I hadn’t been using the two inspector workflow for a while, but had a second inspector buried in one of my tabs.
So probably a lowish priority fix for you guys, it’s not a huge issue for me now I understand what it going on:
