Can't use Arcade to calculate a field

[alex_parij]

Hello. I have a feature class where I am unable to calculate a field despite the fact that Editing is enabled, and syncing is off. I am unsure why this feature is locked out for me:

This data is being brought in via Field Maps where I have leveraged Arcade expressions to populate some other fields automatically, but I don't know if this has anything to do with my problem. Has anyone experienced a similar issue?

Figured it out. I had editor tracking enabled which disables using Arcade Expression.
