Project Load: Importing some .yyzs made with 2024.1300 Betas can cause 2024.11 to lock up

[YYDan]

Description

Importing some .yyzs made with 2024.1300 Betas can cause 2024.11 to lock up - you will get the dialog that the project needs to be downgraded, but the IDE instantly goes into a hang and so you cannot click on anything except the close button.

No errors are logged in the ui.log - it simply stops like this:

[15:39:21:628(6e64)] Importing project 'D:\Downloads\DestroyParticleTest.yyz'
[15:39:21:646(6e64)] Importing 'D:\Downloads\DestroyParticleTest.yyz'
[15:39:21:784(6e64)] Setting ProjectFullFilePathMacro to 'C:\Users\danie\GameMakerProjects\DestroyParticleTest\DestroyParticleTest.yyp'
[15:39:21:784(6e64)] Setting ProjectDirMacro to 'C:\Users\danie\GameMakerProjects\DestroyParticleTest'
[15:39:21:785(6e64)] Setting ProjectNameMacro to 'DestroyParticleTest'

Expected Change

The IDE should not lock up, I should have been able to downgrade and import the project

Steps To Reproduce

1. Download https://github.com/user-attachments/files/18534652/DestroyParticleTest.zip and extract it somewhere
2. Start GameMaker
3. On the Start Page, click the Import button
4. Select the project from wherever you extracted it, then a suitable save location
5. Observe the IDE locks up before the import progress bar appears

How reliably can you recreate this issue using your steps above?

Always

Very related to #9255, but with the added lock-up.

This will be a project that should always trigger it ( it's version is set to 999 )

The issue is now fixed in 24.13+
We can't fix it in 23.11, as it was bad logic in the IDE, rather than anything to do with the project or ProjectTool itself, sadly.
