Fuse preview crashes after build. I have tried `uno clean`, restarting my computer but the problem persists. I am unable to decipher the problem from the log (see below)

Fuse 1.2.1  
macOS 10.13

Thanks,

Did some searching, but couldn’t find a solution. The important bit from the logs seems to be `Sequence contains no matching element`, but where that comes from remains to be found.

I suggest you comment out most of the UX code you have in that project, and see if the app then builds fine. Then slowly start adding parts of the code back and see where it breaks.

That should at least give us an indication on where the root cause of the problem is.

I was able to fix the problem. After I ran into the problem, I opened XCode to work on a different project and saw that some components needed to be installed before I could use XCode. After those components were installed I noticed that Fuse stopped crashing. Very odd.

Thanks

Hey Uldis sorry for the late reply.  
The problem has reappeared. I did a full reinstall of Fuse (using the uninstall script). I’ve tried to create a new blank project and Fuse preview still crashes upon start, this is what shows up in my log file.

Does the entire Fuse program crash, or just the preview app inside it?

Hi, can you also try to run `/Applications/Fuse.app/Contents/Fuse.App/Contents/MacOS/Fuse` so that we can get more logdata?

Hi thanks for your reply.

Anders - the preview app crashes. Upon inspecting activity monitor ‘Fuse’ and ‘Fuse Tray’ are still running.

I was able to fix the issue **temporarily** by running the uninstall shell script -\> restarting -\> re-installing Fuse. It looks like adding the restart step fixed things. Let’s see how things go. I’ll create a new thread if the problem reappears.

Once again this is what happens to be the issue:

```auto

```

About `/Applications/Fuse.app/Contents/Fuse.App/Contents/MacOS/Fuse` do I run it and post whatever shows up in my terminal?

Here is some more info, this is what I get as soon as the Fuse Preview App crashes, there are a bunch of things that are logged before this, but this is what I get exactly when it crashes:

Don’t mean to sound impatient, but I would really appreciate a response on this!

Sorry for taking so long, we’ve started investigating the issue, but we don’t have a solution yet. However running `uno build -t=cmake -r` as long as you have cmake installed (`brew install cmake`), should work fine, but you’ll not get preview support in that case.

Issue seems to have disappeared with the new update. 🙂

Spoke to soon!

We think we’ve found the issue, and will follow up, however are you fine with us sending a custom installer by email which you can test?

~~Hi…~~

~~I’ve now prepared a custom build that _might_ provide some extra information about this crash. It can be found along with instructions [here](https://www.fusetools.com/downloads/channel/custom-preview/1.3.0.14586) (just ignore the “This is an older version of Fuse” warning).~~

~~We’d appreciate anyone experiencing this problem trying this version out and sending us their logs afterwards.~~

EDIT: Unfortunately it turns out this custom version did not log what it was supposed to, so there’s little point in trying custom build all.

Hi Zia, here’s an update…

The forum user Raju has now been very helpful in figuring out a solution to (what looks like) the same or similar problem. It turns out the custom window manager Moom is not compatible with Fuse, and this is likely to be the case with various similar software.

I can’t say for sure that this is the same bugs as the one you’re experiencing, but if you have any software like that installed you could try disabling that and see if that fixes the crashes.

See [this](https://www.fusetools.com/community/forums/bug_reports/crash_on_open_-_v100_mac_os_sierra?forumSlug=bug_reports&threadSlug=crash_on_open_-_v100_mac_os_sierra&page=2) thread for more details.

I hope this fixes your problem, and I’d appreciate any feedback. 🙂

I use the window manager called spectacle, which another user states doesn’t cause problems for them. I have a few other apps on my mac that use access my computer through Security & Privacy -\> Privacy -\> Accessibility and all of them ran in conjunction with Fuse in the past.

Thanks

Thanks for the reply.

So to be clear, Fuse is still crashing for you after disabling spectacle and other software in “Security & Privacy -\> Privacy -\> Accessibility”? Or am I not understanding you correctly here?
