I have the same problem. Changing scene collection (to any collection) or creating a new scene collection causes OBS to crash. I don't get a crash notification or crash log. I've attached a selection of recent session logs. To my reading, they don't point to an obvious cause. I do note that there are a number of other posts with the same issue.
I use NDI and websocket plugins, both of which are up-to-date. I suspected it might be an issue with Elgato Streamdeck but the problem has persisted after uninstalling the software for that.
Any advice very welcome. Thanks!
