A new button that closes the browser

Since the latest update, a down arrow has appeared in the top-right corner of the Brave browser on both of my devices; when I hover over it, it says “Search for tabs.” When I click the arrow, the Brave browser automatically closes (crashes). Sometimes the arrow doesn’t respond at all. I thought it was just on my device, but it’s the same on my other device. Additionally, I downloaded a fresh installation of the browser on a third device, and it behaves the same way.
Version 1.89.132

Before the update yesterday, I didn’t even have that option or icon.

Strange, I do not have that icon, however if I do invoke tab search, it pops up at the very top left of my primary screen, disconnected from the window:

Looks like this feature may be broken. In your case you have an icon that’s supposed to invoke this but can’t, and I don’t but have a menu entry that can, but it spawns off-window.

This is a known issue that was caused by changes in the Chromium code:

We should have a fix for this soon. See this comment for the current workaround.

I am also facing the same issue after the latest update 1.89.132 , did you find a way to fix this ???.

Also toggling vertical Tabs in the settings > appearance crashes the browser in the same way .

Right above your comment.
