Issue description

When I open the project after renaming. Some .tscn files are invalid. Before I renames the project everything worked fine.

If I open the tscn files in the explorer on some tscn, the images are like a blackscreen.
Warnung:
Szenendatei "name.tscn" scheint ungültig / fehlerhaft zu sein.

The errors that occure:
opening the .gd files in the editor did not help

Index out of bounds not only size 5 also other size numbers occure.

Steps to reproduce

I renamed a Project with many .tscn files. Now I cannot open some .tscn. I can only open them if I rename the project back to the original name, but if I do so.
Some other .tscn files are invalid to open.

Minimal reproduction project

I tried to make a minimal project by renaming but could not reproduce the issue. Maybe the issue occures on larger projects.

What I found out is: renaming the project with the same name does fix it sometimes on startup. So that no errors occure

4.1.1 has some serious bugs that can cause scene corruption when renaming files. The good news is that the bugs have been fixed in 4.2-dev5. But the bad news is that it appears there are no plans to back port the fixes to 4.1 because it's a big change that might introduce other regressions. My advice is to use version control software and always commit your work before renaming anything so you can revert if things break.
