The level does not open after deleting folders

I reinstalled the program, but the problem did not go away. According to the tutorial from YouTube, I wanted to take a file from auto-save and use it. But the difference is that the person did it, and the auto-save file uploaded to the ue5 work folder via Explorer was also shown in the content browser, but it is not displayed in mine. When trying to create a level named autofiles, the content browser tells me that such a file already exists, although it is not displayed in the content browser
