Additional Information

Thanks for report @dodieboy,
do you have sync enabled?
do you have Brave Rewards enabled?

I tested on my iphone 8 with iOS 14.8.1 and I can't seem to reproduce it

[dodieboy]

Brave reward is disabled, sync bookmark is enabled, sync history is disabled

[iccub]

@dodieboy can you check it with disabled sync?
does it matter whether you enter a url manually or visit a top site?

I'm trying to narrow down the problem, could be this specific iOS 14.1 crash, we are still waiting for crashlogs to show up

[dodieboy]

The application crash both using top site and manual keying of website, even click the report bug from the menu.
Tried disable sync, it still crash

[dodieboy]

I also tried disable brave shield, it still crash

[iccub]

@dodieboy if you have diagnostic usage enabled on iPhone can you try retrieving crash logs from your device?
You can follows steps from here https://help.dropbox.com/installs-integrations/mobile/ios-crash-logs#iphone

In the Diagnostic & Usage Data you have to look for Client.app entry, this is how our app is named if it does not show up as Brave.
If you are able to post it here that could help us resolving it quickly

thanks @dodieboy,
we are still investigating, looks like it's iOS 14.1 specific problem,
on newer iOS 14+ versions it does not happen

It is related to us moving to use a thing called content worlds when evaluating javascript
https://developer.apple.com/documentation/webkit/wkcontentworld

[iccub]

We found a fix, this will probably land in our next builds pretty soon.
Only temporary workaround is to update your iOS version to 14.3 or higher :(

iOS 14.1 verification PASSED
video proof:

[iccub]

Hi, build with this fix is live, you can update from App Store manually

[dodieboy]

Great work to the brave IOS developer team, manage to push out a fix in a short time. I have downloaded it and using it with no more crashes
