Brave rewards crashes Windows 10 and Linux Mint

Hey friends. Here’s the problem. I’ve been using the browser for some couple of years now and recently (2 or 3 months) I started to experience hangs on my desktop (Win10 H.D.D) and my laptop (Linux Mint S.S.D) which I realized is because of high H.D.D usage on both platforms. Then I read somewhere that’s because of brave reward. So I turned it of and the issue solved. Yesterday I turned the reward back on once again and the same issue occurred again and shutdowns came back to both my computers.

I really don’t like to turn rewards off cuz it’s brought me about 500 BATs so far.

Please help.
