WindowsError: [Error 193] %1 不是有效的 Win32

the last word means: WindowsError: [Error 193] %1 It is not a valid Win32 and sometimes when youtube-dl download failed(time out or other bugs), click the delete icon ,hint “can’t remove”，then click the “X” icon,The window is not responding.this is hard to reproduce,so I can’t capture.
