Where is the workspace go?

i am sure i did not remove it
how could i be sure where did it go?

If deleted then go to the Deleted Document doctype and restore them.

Otherwise update the ERPNext and check it.

i have some works now
i will check after update the app
but in another site the workspace is still found this mean there are not any know relationship between the update and the issue

Not idea, Maybe someone delete the workspace and also delete from deleted document doctype.

there is log or any thing to make me sure in frappe framework help in this issue?

There is no store log.
