### Issue description

I have been using Godot on an Azure VM (Ubuntu) for a few months with no issues. Yesterday, however, the editor started crashing a minute or so after opening my project, with no error message.

> edited to remove MRP, as that introduced a _different_ (known) bug

Here's the verbose output of my actual project: [godot crash - game server project.txt](https://github.com/user-attachments/files/16192826/godot.crash.-.game.server.project.txt)

Start by reviewing the attached verbose output, then reproduce the editor crash in Godot v4.2.2 on the specified Ubuntu 22.04 Azure VM environment. Done means identifying the cause of the illegal-instruction crash and documenting or fixing the issue.
