Nylas N1 (the latest Windows build) appears to have updated itself to Nylas Mail, and now refuses to start. In the AppData/Local/nylas folder, the app is now launching from app-2.0.10 instead of app-1.5.0 (which is still there). When it launched, it opens 3 instances of itself, and in each, opens the dev console immediately, displaying the following error:

Since Nylas Mail isn't released yet for Windows, I'm fairly sure this is in error.

I have also just recieved this error. Any help would be appreciated!

[michaelmulligan]

Likewise, same error. Any workarounds until it's fixed?

[hallamoore]

There's not really a work around, but I'm working on a hot fix. Should be out within the hour!

[hallamoore]

This should be fixed now, but you may have to delete that app-2.0.10 folder or reinstall 1.5.0. (There should be an executable at https://github.com/nylas/nylas-mail/releases/tag/1.5.0)

Let us know if there are any more issues~

[jstejada]

The windows build has been fixed. If you've downloaded a bad build, you can re-download it from nylas.com/download

Hi, I tried to install 'npm react-alert' package and as soon as it was installed, nylas stopped working with the message saying 'Cannot find module 'isomorphic-core' at Module._resolveFilename'. Could anyone please help me with this.
