According to quick search, this is at least 4 years old bug so this is likely to be duplicate but I don't understand Github's Search and it didn't show me anything so I am reporting it anyway.
Here are users complaining about it after following a tutorial by @NathanLovato

If you need help with testing this, I am willing to help out as much as possible. This bug is single handedly demolishing my project and I would love to see it fixed.

Furthermore, this sometimes resets the exported variables if you change the script.

Maybe related? #69360
I created a PR for that last year. Can you test it?
#69362

[CarpenterBlue]

I can confirm that the Preload in a Autoload is the issue.
As for testing the PR, I assume I will have to compile Godot which I never done yet, I will give it a shot in few days.

[CarpenterBlue]

Ok. Sorry it took a while, I tested the PR and can confirm it fixes the Issue!

I think that this still happens in godot 4.1 too

This issue does not contain an MRP or clear reproduction steps, but from the conversation it looks like the same issue as #69360, which is 3.x exclusive. Since this issue does not contain any reproduction information I'll close it as duplicate.

If you are running into an issue with exports and preloads in 4.x please open a new issue with an MRP.
