PC cannot boot up and require new installation of Windows

Hello there,

I have a Brave browser and collecting BAT for almost a year. The only thing is I do not connect it with a verified Uphold Account. Last few days, my laptop wouldn’t boot up so I have to do back up for my hard drive manually using external adapter. If I just copy and paste the Brave folder from Program Files, will I still be able to get back my current BAT available inside the Brave browser without losing it? or is it reset to 0 back? I hope somebody can help me.

Thank you.
