Brave freezing when opening a window

Hello,
I use Brave for like 2-3 years now and I never had any issue with it but since i would say 1-2 weeks, when i open a tab like my mails, Brave freeze and this window crash and ask if i want to wait or close, but more i wait more window has this issue, now it’s my excel, youtube etc …

I don’t really understand what’s going on but i really need help or i will leave Brave because i need everything fast in my job.
Thanks
