The Brave Browser's initial launch lag never goes away.

After installing Brave browser, the first launch takes a very long time. Sometimes subsequent launches also take a long time. I’ve tried everything. Flags don’t work. Commands I’ve entered into files don’t work either.
Kwallet is misunderstood. Kwallet doesn’t block it; on the contrary, it helps it work.
The problem isn’t related to the system or Kwallet; the problem lies in the browser’s basic configuration.

When the Chromium-based Opera browser was first released, it also had the same problem in Linux environments, but they eventually fixed it.

Brave is the main browser of the Besgnulinux distribution.
I can’t make it the default browser while this problem persists. So the problem isn’t personal.
However, I never want to give up on Brave.
I kindly request that you try to resolve this issue.
Regards.
