Crash when baking shadows in CPUlightmapper

[SkanerSoft]

Godot version:
Godot 3.3.1 Stable

OS/device including version:
Windows 10 x64

Issue description:
Baking shadows instantly crashes. Godot crashes without any entries to the console, which also immediately closes.
Everything works well in 3.3.

Steps to reproduce:

1. Create any scene with meshes
2. Bake the shadows

Minimal reproduction project:
Any project.

Once again, I note that in 3.3 everything works fine. However does not work completely in 3.3.1.
In the evening I will try to somehow get the possible error messages, but so far it has not been possible to do so. The engine just closes when the "Bake" button is pressed.

To get a crash backtrace, run the editor from a terminal.

To get a useful crash backtrace (that points to functions causing the crash), you need to compile a Godot build with debug symbols included since official releases don't include debug symbols.

Dupe/related to #48822?

It's probably a duplicate of #48822 yes. Could you test the build I linked there?
