:( I don't have a solution but wanted to say this has been happening to me too, i downloaded it about a week ago and it was working fine for a day or so, but now closes constantly and i'm not sure why. i tried even opening a newly downloaded version and it does the same thing..
I asked about this in the discord and was told it has to do with Webroot if you have it as a virus scanner. It bypasses your command even when you set the file as "okay". Was then told the only way to address this was to uninstall Webroot, which I'm not going to do, so probably best to just stick with the browser version.
If you don't have Webroot, then I'm not sure what your guy's issue is but it might be a related thing to your PC's protection.
