Scene Editor crashes when loading a file from *specifically* Sonic Mania

[c08oprkiua]

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

Expected Behavior

Opening the scene as expected.

Actual Behavior

Gets to 80% (according to the terminal printout) and then segfault.

Steps to Reproduce

1. Have your RSDKv5U executable with an extracted Sonic Mania Plus (version 1.07.0034) in the same directory (as if to play the game)
2. Attempt to load any stage file from the game into the v5 stage editor

Screenshots

No response

Was another editor used on the file(s)?

No.

Platform

Linux

Additional Comments

• This seems to only apply to Sonic Mania stages.
  • I can load mods for Mania, and I can load other RSDKv5U projects (such as MegAmi's Pong) without issues.
• The data folder is not corrupted since I can load the game normally through the RSDKv5U executable.
• My directories in the GameManager are all set properly, as I was able to run Pong (which I keep in a different folder with a different executable) without issues from RetroED, and set them back to double check.
• From my brief poking around in QT Creator (not familiar with it), it seems it's something going pear-shaped when initializing the game link
