Scripting define symbols empty

I'm working on Unity 2022.1.4f1 (Ubuntu Linux). When I try to define symbols in the project/player settings, they are actually written into the project settings asset and the .csproj file.
However, after Unity recompiles scripts, all the entries are removed from the list, both, symbols and compiler arguments.

I accidently added a symbol as an entry to the arguments list and Unity failed to compile. I had no chance to remove the entry from the list in Unity.
I also tried to reimport all and regenerate project files without success.

Therefore I had to close Unity editor, search all occurrences in the project folder using the IDE and remove the compiler arguments manually.

Why could this happen? Do I have any chance to manage symbols and compiler arguments from the Unity editor?

 

Not so sure about compiler arguments but for script defines, that should be the only place you manage it from.

Make a blank project, try it there. We know it works.

It could fail for various reasons, such as a rogue editor script running and removing all those defines.

Either way, please consider using proper industrial-grade enterprise-qualified source control in order to guard and protect your hard-earned work.

Personally I use git (completely outside of Unity) because it is free and there are tons of tutorials out there to help you set it up as well as free places to host your repo (BitBucket, Github, Gitlab, etc.).

You can also push git repositories to other drives: thumb drives, USB drives, network drives, etc., effectively putting a complete copy of the repository there.

As far as configuring Unity to play nice with git, keep this in mind:

It is only simple economics that you must expend as much effort into backing it up as you feel the work is worth in the first place.

It seems you are experiencing this bug possibly?

ALSO: when you type a define symbol in the box in Player Settings, make sure you press ENTER!!!!

Failure to press ENTER will simply cause Unity to drop the change(s).

 

Yeah, it sounds like that.

 

Adding symbols actually works behind the scenes. The only thing is, the are removed from the list in the Editor GUI. Thus removing them manually in Rider is the only chance to get rid of them.

 

i can't change the define symbols in android, they keep going back to their desktop settings now

 

So, I'm getting a mismatch between what's in the ProjectSettings.asset file and what's showing up in the Editor.

Currently on 2022.1.13f1. I know it's old, but I haven't heard of an editor that has fixed this and I'm not changing versions if I don't know it will fix my problem.
