[Scene Editor] Crash when having v5 and pre-v5 Scene Editor tabs open simultaneously

[Lavesiime]

Before opening this issue, I ensure that...

• I have checked both open and closed issues and confirmed this bug has not already been reported.
• I am not asking for tech support (e.g. error when starting program or trying to build).
• I am not reporting an issue with assets/scripts/logic of a specific game/mod; this bug is directly related to the editor itself.
• This bug is not related to any unofficial forks of the editor, and any issues with those should be kept in the appropriate repository.

Editor Tool

Scene Editor

RSDK Version

v5, v4, v3, v2

Expected Behavior

The editor continues to show entity renders normally in both tabs and does not crash.

Actual Behavior

The editor crashes.

Steps to Reproduce

In my testing, it's been hard to pinpoint exactly steps are are required to reproduce this bug, but here are the fewest number of steps I've found to be able to cause the crash:
(for further context - this testing was done on S3K through S3KOEditorLink)
0. In RetroED, set up a Base Data Folder Location for v5 as well as any legacy engine version (tested with v2, v3, and v4) so that the game link would correctly load.

1. Set up a v5 mod folder that contains a GameConfig as well as a scene folder. (in my tests, i just used unmodified files copied straight from the game)
2. Open the stage contained within the mod folder, and choose the mod's GameConfig instead of the one located within the Base Data Folder. Entities should be correctly loaded, and the editor should work fine thus far.
3. Open a new pre-v5 Scene Editor tab (whether through Recent Files or manually opening a scene). Once again, entities should appear just fine in this tab.
4. From here, attempting to switch back to the v5 tab should cause the editor to crash. Sometimes, the crash happens when just clicking on the tab. Other times, however, the editor allows you to successfully switch back to the tab, but several (not necessarily always all) entities will no longer have renders and the editor will crash a second or two later.

Screenshots

No response

Was another editor used on the file(s)?

All files mentioned in the steps above are stock files, none of them have been modified (in RetroED or any other editor in general) from their original game files.

Platform

Windows 11

Additional Comments

The crash only appears to happen when opening a v5 scene and then a pre-v5 scene - when opening the in the reverse order, everything appear to works just fine.
