That happened to me also. It’s not the crash bug, that’s different: https://github.com/brave/browser-laptop/issues/13947
In this case, Brave does not crash, but instead, just hangs the browser tab and becomes unresponsive. The overall Brave user interface still works, but nothing in the tab works.
I had the Shields enabled (Brave lion icon is orange), then opened https://www.chase.com/ in a new tab. I get really sluggish response, and high CPU usage. The Chase website fails to load completely, it still displays spinning arrow graphics from Chase.
The workaround is to turn off Shields in that tab, then open another new tab, and try https://www.chase.com/ again in that new tab. Attempting to re-use the existing tab, that was trying to load Chase, appears broken: clicking the Stop button does nothing, and the address bar becomes unresponsive.
I’m running Brave version 0.22.667 on MacOS.
