The update manager in Linux Mint updated libllvm15 and now Brave is completely unusable for me. Is it possible to fix this without using a system backup?

Brave is my primary web browser but every page I visit isn't being rendered correctly at all and some pages are completely broken. I have a system backup from a few days ago but I'd prefer not to have to use it if I can. I think Brave is the only thing that was affected but I think I should try to revert the update if it's possible.
