I have this problem in Unity 2022.3.23f1

Unsupported type Vector2f
UnityEditor.EditorApplication:Internal_CallUpdateFunctions ()

constantly and I don't know where it is coming from.

Ok, just saw this error in Unity 2021.2.12.
It started after I changed an already existing property from float to Vector2.
It was a private property but exposed to the Editor through the use of [SerializeField].
After that, I started receiving the "Vector2f" error, every time I changed ANY Vector2 in that script.
But only for the objects in the scene that were instances of a prefab!
I have other objects with the same script, that were not instances of a prefab, and those were not affected.
My solution was to remove that property and recreate it anew but with another name.
I had to retype some data in those objects, but better than having the error all the time..

2021.2.7f1c1 could still reproduce this error!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
