Nothing Works in 2020.1.7

Beginner Questions
#1

Basically, after I import, all the scripts in the folder are shown as white in the project tab and I cannot open them directly from unity, I don’t think unity even recognizes that they are scripts. On top of that, I cannot use scripts, unity treats them as if they don’t exist. I don’t know if this is a unity bug or because this project has not been updated to 2020 yet.
When I had used Astar earlier in 2019, it had worked fine.
Thanks in advance!

Hi

Are you seeing any errors in the console?

#3

No, I don’t see any.
When I search for the component it just doesn’t show up as well as when I go into the package, the scripts are shown as blank files (not c# scripts and cannot be opened in VSCode)

#4

Try to delete the package and import it again.

#5

I tried that and it did not work, but I just made a new project with the same unity version and it worked, pretty weird but I guess its fixed! Thanks for the quick replies!

I have a similar issue, the system is not working in the project where i want to use it, not even the example scenes, if i hit play nothing happens, no log errors, nothing. If i import this in a new project, everything works fine, I have tried in Unity 2019.4.11f1, Unity 2019.4.12f1, and 2020.1.9f1, I have also tried A* 4.2.15 version and also 4.3 beta, same result, can you help me?

AstarPath.Update () (at Assets/AstarPathfindingProject/Core/AstarPath.cs:859)

I’m not sure what could cause that. Are you using any managers that might end up messing things up?
