Actually figured out how to fix this. I’ll post here to make sure if this happens to anyone else, hopefully it can be fixed with the same process.
Brave Settings > Additional Settings > Reset Settings > Restore settings to their original defaults
History, Bookmarks and Saved passwords will NOT be deleted, you just have to set your settings and extensions back to the way you had them and boom, that 2-3 second lag is gone.
I’d still like to see Brave fix whatever issue is causing this though.
