Alt-tab-macos: 5.0.0 crashes right on startup
Describe the bug
This morning I was created with notification to update to 5.0.0 which I did.
After the upgrade step, nothing happened. No app icon visible but also cmd-tab didn't work. Not even the native one 馃槄
Luckily I could use cmd-space and also HyperSwitch was still activated cmd-tab from there (I still use it for in-app switching as AltTab doesn't support it).
After re-downloading (same effect) I found out some things:
- the app does start for a brief moment, showing what instead should be an app icon for ~1s white rectangle in the top bar which then disappears
- I found something in the console.app

I still don't understand why the _native_ window switching doesn't work at all currently so that's why I continue using HyperSwitch for that.
(I don't want to reboot right due to project I'm working on )

Hey @mfn! Sorry to hear that v5 is not working for you!
Could you please run this and share the results?
defaults read com.lwouis.alt-tab-macos
Apparently the crash reporter shipped with AltTab crashed when trying to read the crash report as well:
default 08:55:55.001614+0200 AltTab [AppCenterCrashes] WARNING: -[MSCrashes handleLatestCrashReport]/1039 Couldn't parse crash report: An unknown error occured decoding the crash report
The root cause may be with ShortcutRecorder who reports a critical error:
#Critical SRKeyCodeNone has no representation in Carbon

I made a local build from @akx quick-fix PR: AltTab.app.zip
@mfn @mparry can you try it and see if it fixes the issue for you?

@akx I don't get anything in the debugger when running AltTab. Did you activate any particular option in XCode, or did anything special? I'm not seeing this assertion failure, thus why I assumed it's working fine
lwouis

@mparry @mfn @akx could you please try this build as well? I brought back the previous code for the "Quit" button on the top right of the preferences window, which is printing layout warnings. It may still be fine despite the warnings, so I would like to know how it goes on your guys machines. Especially try switching between tabs in the preferences window.

Nothing special that I can tell, but I'm hardly a seasoned Xcode pro (if anything, it's one of my least favorite IDEs).

This issue is also happening to me, though using the newest build that is linked above fixes it.

@akx which version of XCode are you running? On which macOS version? Could you share a screenshot of how the error is presented also?
I'm really curious to understand why I don't get this error and you do. It's impacting some users, and I had no way to know because on my local machine there is no error in XCode, and the app runs perfectly.
Here are my settings for XCode debugging:

App updated this morning and it started to crash. Only way i was able to have it launch was to take the permissions out. as soon as i enable them back on, it crashs again. Uninstalling and cleaning the config files doesn't help.
While disabling the permissions i was able to submit a crash report.

Luckily I could use cmd-space and also HyperSwitch was still activated cmd-tab from there (I still use it for in-app switching as AltTab doesn't support it).
btw @mfn, this has been available for a while now in AltTab in Controls > Shortcut 2. Am I missing something maybe?

@franciscoafonsoo everyone else reporting a similar issue seem to be doing great with the build linked above. I will release that build (+ other improvements) soon. Could you please test the build linked above and share your results here? Thanks!

Inexplicably, v5.0.0 began working now that I tried again. Since we're talking layout things, I wonder if this had something to do with multiple monitors...

@lwouis Installed the build you linked above. It pop an update for 5.1 (refering to the PR) that i did. Everything is back to normal now. Do you need any more information ?
Btw: this was super fast to resolve, thanks to everyone involved !

@lwouis thanks so much for that, I guess I can finally ditch HS 馃檹

@franciscoafonsoo if 5.1 works for you then it's all good 馃憤
Thanks everyone for helping on this issue! Special thanks to @akx who actually found the root cause and saved the day! 馃嵕
I wish I could have dug deeper on the crash, but unfortunately on my local machine I was never able to reproduce the issue, and only made a in-theory fix in 5.1. In the future I would like to re-explore the code I had to remove in 5.1 because the current code generates layout warning so potentially could have issues on some machines (layout issues are indeterministic).
