OBS hangs/crashes on opening filter window of DSK scene

[superplex25]

OBS seems to crash if I have multiple DSKs with most of them having output sources chained together, and I enter and exit the filter menu of a DSK scene multiple times.

Windows version: Windows 10

OBS version: 31.0.4

Downstream Keyer plugin version: 0.3.3

Expected behavior: I expected OBS to not crash at all, and instead open and close the scene filter window without any problems.

Current behavior: After opening and closing the filter window on a DSK scene a few times, OBS hangs and then crashes.

Steps to reproduce:

1. Make 7 DSKs, and 7 scenes that each (except for the topmost one) have a different output source.
2. Link each scene to a DSK.
3. Set up each output source so they are linked to one another (second to topmost DSK output linked to previous DSK, which has another output source linked to the previous one, etc.). Ensure the bottom output source is linked to the Program output.
4. Open and close the filter window on one of the DSK scenes multiple times. It should take only a few times of doing that before it crashes.

Unfortunately, this crash causes OBS to not return a crash log, so I cannot provide that, and the regular log file does not have anything of use as it ends on the switch to the scene that I open the filter window on.
