Brave Browser Beta Bug report: crash

All Brave-created web apps crash on launch in macOS Catalina beta:

app_mode_loader[42152:5297055] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[NSAccessibilityRemoteUIElement accessibilityTitle]: unrecognized selector sent to instance 0x7fdd1fd5d2c0'

System

Brave Version 0.69.113 Chromium: 76.0.3809.100 (Official Build) beta (64-bit)
macOS Catalina 10.15 Beta (19A536g) on an iMac Pro desktop

Timeline

Brave Browser Beta Apps (app_mode_launcher) throws NSInvalidArgumentException instantly on latest macOS Catalina beta.

Visit e.g. https://discourse.devontechnologies.com/a support forum
Brave suggests a small plus sign, to “create app” from web site
Click the plus sign, Brave saves the web site as “Sitename.app” in ~/Apps
Launch the App by either doubleclicking or right-click and “open”
Crash

Expected result

I expected Brave Browser to open a new tab, with the corresponding URL to the forums

What happened

Running the launcher manually from the terminal (iTerm):

Contact me for whatever extra details I can provide.
The new macOS beta or final will probably come soon; will update this post as soon as that is deployed.
Thank you for an awesome project, browser and community. THank you all.

This still happens. Were you able to find a workaround?

Mattches · December 4, 2019, 4:38pm

@mdbraber,
Can you tell me what site are you trying to “install” so that I can test on my end and see what the problem may be?

mdbraber · December 4, 2019, 4:41pm

Tried this with fastmail.com and community.brave.com - both crash instantly. Gave some more background in this Github issue: https://github.com/brave/brave-browser/issues/7205

Mattches · December 4, 2019, 4:48pm

@mdbraber,
On my end, I was able to create a PWA out of community.brave.com without issue – also running macOS Catalina:

Can you tell me if you have any extensions installed in the browser?

mdbraber · December 4, 2019, 5:15pm

@Mattches well that’s good news that it works on your end! I have a completely new installation with no extensions. Could it be something else in my configuration?

Mattches · December 4, 2019, 5:36pm

@mdbraber,
Do you get the same error by going to Menu --> More tools --> Create Shortcut?

mdbraber · December 4, 2019, 6:39pm

Yes, unfortunately the same error

mdbraber · December 4, 2019, 7:14pm

After some digging I’ve found that BetterSnapTool (https://folivora.ai/bettersnaptool) seems to be causing the problems. I’ll try and see if I can find what exactly is causing this and why it’s actually causing Brave to crash (and not BetterSnapTool). It would still be interesting to understand why Brave is not catching the exception thrown.
