I ended up deleting the animation item from the workspace selector, and i don’t know how to arrange or access the animation otherwise
Hello and welcome to the forum
If you delete one of the default workspaces, such as Animation, then it should reappear in the Workspaces list after you restart krita.
Did it reappear after you restarted?
You can make your own workspaces and save them to that list.
Settings -> Dockers shows a list of all dockers and which ones are active, i.e. on the current workspace. You can turn them on or off from there and then drag/resize rearrange them in many ways to suit your preferences.
Then you use the workspace chooser to Save whatever arrangement you have as your own personal named workspace.
The manual has lots of information about this and other things in krita:
