@HalAdam Can you do me a favor and upgrade your Brave browser to the latest and try launching Brave from the command line using the following?
brave-browser --js-flags="--nodecommit_pooled_pages"
If you need to go back to the last working version, you can do the following:
sudo apt install brave-browser=1.71.123
sudo apt-mark hold brave-browser
I’m typing out this reply on “Version 1.73.105 Chromium: 131.0.6778.265 (Official Build) (64-bit)” with the flags set above. So far so good, but I have limited runtime.
Edit: I’ve been browsing for 2 hours without crashes. This may not fix the issue, but as a workaround, it seems to lessen the frequency greatly.
