Brave Browser refuses to launch on Lubuntu 24.04 (LXQt)

Updated Lubuntu to 24.04
Brave-Browser stopped working, will not launch.
Started from the terminal, got the following:

Uninstalled brave with --purge.
Re-installed, same problem.
Why did it break?
Why does it seem impossible to fix?
Right click and half of everything else doesn’t work on this stupid firefox browser, and chromium keeps escalating its resource until it crashes my system. Brave was a good option before, but now I am questioning that too. Are all the browsers complete garbage?!

i can not help but wanted to extend this error message another month.
i have the same issue on Linux Mint 22.

It worked just fine a few days, suddenly it did not start up anymore. Same error messages as you have…
