Reproducible in: 4.5.beta [0dd9178]
Not reproducible in: 4.5.beta [8acc596]

Issue description
When running --headless --import on seemingly any project that has any autoload singleton, you get the following crash: signal SIGSEGV: address not mapped to object with this backtrace:
SceneTree::get_root() const (scene/main/scene_tree.h:300)
EditorAutoloadSettings::init_autoloads() (editor/settings/editor_autoload_settings.cpp:454)

OS_LinuxBSD::run() (platform/linuxbsd/os_linuxbsd.cpp:975)

Which seems to be because this error gets tripped:
Lines 505 to 508 in 0dd9178
This seems to be a regression from #108893.
Steps to reproduce
- Run Godot with
--headless --importin the MRP. - Note the crash after the
first_scan_filesystem | Creating autoload scripts...step. - Also note the error saying
ERROR: Parameter "data.tree" is null..
