Visual Glitches and Crashing with Certain Map

Describe the Bug
I’ve been working on a map for several weeks. It’s relatively large, but not huge. I’ve begun randomly seeing very weird visual artifacts and glitches in the map a couple weeks ago (screenshots attached). They appear and jump and morph around from certain angles. Note that there is NO geometry near the camera when these glitches appear. Often, reloading the map will get rid of them temporarily.

More concerning, I’ve reached a point where I’m trying to use a hide volume to hide some lights (screenshot of location attached). Every time I try to make a hide volume in this room, TaleSpire crashes (log/dump attached as well). I seem to be able to create hide volumes in other places, but not on these lights. I’ve tried clearing cache and even published the board and re-imported, but all issues persist (including visual glitches).

To Reproduce
Steps to reproduce the behavior:

Open board (talespire://published-board/U2hpcCBJbnRlcmlvcg==/94625c4a41c1e70dec7fad945c35c125)
(For visual glitches) Move camera to certain angles, shown in screenshots.
(For crashing) Create a hide volume that includes ANY of the floating lights in the room shown in the screenshot.
TaleSpire crashed.
