If in Electron you try to reload using the menu View/Reload or View/Force Reload it will give a blank page and the following errors in the logs:

checkForUpdatesAndNotify called, downloadPromise is null
(node:197023) electron: Failed to load URL: file:///Cristal/#/ with error: ERR_FILE_NOT_FOUND

It seems that the URL has been changed to something invalid in the Electron context.
