OSX app always crash on first launch

[metalelf0]

Hi,

just downloaded the latest release and I cannot start fvim from osx.

Here's the window I get with the error message:

Currently installed neovim version is NVIM v0.5.0-53b0258. OS is macOS Catalina 10.15 (19A602). Let me know if I can provide any further info.

Thanks!

Hi @metalelf0 !

Thanks for reporting.
Can you start nvim in a terminal?

[metalelf0]

Yes, I use it regularly. Strange thing is, I just tried opening fvim again, and it started normally (just a couple warnings about ginit.vim, but nothing critical). The message I posted above has been shown only on first start.

Other users also report this symptom. Weird indeed.

I've edited the title a bit. Let's keep this issue open so we can track and fix this.

I've got this issue too.

In my case most of the times it crashes. I am very lucky to get it working. I get a blank (black) screen.

I don't get crashed anymore :)

Some findings here. The crash usually doesn't reveal the "real exception" but if you go into the app package folder and invoke fvim-osx-launcher, the exception will be printed to the terminal.

I've got a null value exception caused by $HOME not set in the launcher environment.
Working on a new launcher script that will solve #86, #145, #128
