Projects failing to load

My student reported a crash, after which her project fails to load with the following error:

ccpnmodel.ccpncore.memops.ApiError.ApiError: Linked-to object with ID not found: <ccpnmr.gui.Window.WindowStore [None]>:nmrProject:default_user_2019-08-22-11-46-47-642_00001

So far all attempts to recover the project by copying xml.bak files has failed.

can anyone help?

Hi, Do you have the full error message? Are you able to share the project with us?
