The title says “when hovering over inventory items”, not “when starting a game”.
The OP stated that it is happening in “PTR 2.6.10”.
Blizzard has asked us to report PTR bugs in the PTR Bug Report Forum.
The thread I linked to has reports of the PTR freezing under various conditions. That’s why I said: “It may be a similar issue…”
If keifaln does not think it is a similar issue they can always move this thread to the PTR Bug Report Forum.
