Seem like some genius at Epic made a mistake. Every time the JSON at ‘C:\ProgramData\Epic\EpicGamesLauncher\Data\DownloadManager’ is populated with any data, it makes the launcher crash. You don’t even have to delete the file, if you just open it in notepad, remove the content and leave a [ ] - it works as well.
So my guess, there won’t be a way around it until they patch whatever it is that causes it to crash. Just remove the json or change the content to [ ] and wait for an update, I guess.
Very annoying, but whatyougonnado?
