Thank you very much for your reply
Other projects have no errors, only this one project has an error, it can't be opened after saving, the solution file in the background folder is still there, but only this project is open with an error, the workbench interface is blank, and the storage paths are all in English, there is no problem with using it before,
 How to recover the data as much as possible, there are about 190G solution results，thanks
