Error on initializating Workspace on a newer version

So, i tried updating my mod which i thought i haven't touched with any version that wasn't 2021.1, so i opened with it, and the workspace gave me an error saying it was opened with a newer version, so i used 2021.3 and now when i try to open it, the console of the workspace gives this error:

And i don't know what did happen to the workspace do this, because as i've already said, i haven't touched the workspace without any version than 2021.1 until i decided to open it today and this happened
