Why I can only update a user's data in ASP.Net Core with Identity? - asp.net-core

Question

I was testing my application and I saw that I can only update the information of a single user and not that of the others, the application does not give me an error message or anything, it only reloads the page and the data does not reach the database data, whereas with a single user this does not happen.
