Hello everyone and sorry for late replay
@bluess you said you make clean install just to make sure we on the same page
- uninstall brave
- remove the data folder which you can find here
notice that step 2 will remove all your profiles data like reward password bookmark history everything so backup the data you want before delete that folder
- install brave again
if that what you did then ignore the above
could you try to create new user account for mac (not brave profile) and see if brave work as expected in that new user account
i will borrow one idea from @JimB1
so @bluess could you close brave then change the default language of the operating system to english then open brave again and see if it work fine using the english or not
hope any of the above help and have a nice day everyone
