Community + Sync problems windows

i changed my laptop and i did not get my sync password. Plus, i cannot link my rewards to my uphold wallet since there is more than 4 devices linked.
I still have the appdata folder from my last PC maybe i could find a way to sync all data and link my new brave to the uphold wallet (if i can remove devices).
Moreover, The community pages do not load on my brave browser and i do not know why.
