Random message on system start "We detected an issue during the last launch"

howdytom

Why does Orion randomly show the following message on system start: We detected an issue during the last launch?. When I hit update, Orion is already up-to-date. I havne't set up any profile or extension. It's a basic installation.

Open Orion without warning message

macOS 15.7.4 Orion Version 1.0.4 (143)

8 out of 10 times, the message shows up. It feels so buggy. This has been an issue for a long time. I notice this bug on multiple machines.

Sadly Orion is not yet ready for Production.

howdytom The message only appears if Orion crashes (or exists due to force quit or terminated by OS) before completion of initialization during launch (kind of detecting launch failiure).

Can you please check for crash reports in Console (if there's any Orion crashes), and share that with us.

And the above feature is to avoid crash loop, where even updating to new version becomes impossible for some users.

I understand the frustration when you hit some issue repeatedly, but unfortunately we are unable to reproduce that, and same for most of other users. So, we request your help in identifing root cause with more data, to help fixing issues, as we relay on our contributers like you to be able to make Orion better.

howdytom

dino Well, Orion does not crash at all. There are no CrashReports showing up in the Console. In the meantime I have upgraded to Orion 1.0.6.145. Next time I quit and reopen Orion, the message shows up again.

dino

howdytom if this still happens, can you please try running Orion from Terminal:
./<Path>/Orion.app/Contents/MacOS/Orion, and share logs from terminal console.

As, I doubt, there's can be some silent internal crash happening on Orion launch which breaks further execution where we are setting flag for successful launch. Your logs can help us fixing this.

howdytom can you try relaunching Orion again, as I am sure you will not see that launch failiure message this time, as I counldn't see any critical failure in your logs. Let's try a few more times, to check if we get any critical error info in console, and even if that launch failure message is showing-up, we will need to dig the issue deeper to find the root cause.

howdytom

dino I have opened and closed Orion Application 2 times, using CMD Q. Starting the Orion a third time the message shows up again: We detected an issue during the last launch.

{We detected an issue during the last launch.?}

dino

howdytom can you please try opening Orion using Terminal only for a few time and copy logs to some text file every time until this above message appears, as one of those luanches might had launch failure crash and we want to catch that, to be able to fix the issue. so we need your help, as you are able to reproduce the issue easily.

dino There is still no CrashReports showing up in the Console, although I have opened Orion multiple times. I do experience the same issue on a MacBook. These issues should be addressed by the development team. The current state feels really buggy and annoying. I do not want be beta tester.

dino

howdytom We are investigetting this, and as there's no crash report, this means the flag is not getting synced with disk timely for some reason, and might be causing the issue. We are debugging and trying to find root cause of this, soon we will ship the fix.

howdytom

@dino Unfortunately the bug still exists with v1.0.8.147.1. Starting Orion three times the message shows up again: We detected an issue during the last launch. It's a pity

dino

howdytom it's really strange. but we will try checking this again. Can you try one thing please, download clean build and replace your original build in Applications with that.

howdytom

Your download link for 147.1 shows as incompatible. I am using macOS 15.7.7

dino

howdytom oops.
https://cdn.kagi.com/updates/15_0/147.1.zip for you

howdytom

dino Thanks. I have removed and copied the new version.

I have opened and closed Orion Application times, using CMD Q. Starting the Orion a 2nd time the message shows up again: We detected an issue during the last launch.
