The Build progress window and Launch Screen break when another project of the same editor version is closed during the build process

How to reproduce:
1. Open two projects with the same Editor version
2. Build one project
3. While building the project, close the other project
4. Observe the Editor of the project that is building
5. Open the closed project again
6. Observe the Launch Screen

Expected results: The build progress window does not disappear, and the Launch Screen is in the foreground processes
Actual results: The build progress window disappears, and the Launch Screen is in the background processes

Reproducible in: 6000.2.0a9, 6000.2.10f1, 6000.3.0b8, 6000.4.0a3
Not reproducible in: 6000.0.61f1, 6000.2.0a8

Reproduced on: Windows 11 Pro (24H2)
Not reproduced on: No other environment tested

Notes:

• All processes work fine in the background. The problem is only visual
• The bug is in effect until all instances of the Editor are closed
