i know many of the following setting is not related but let us see how it go
all setting in brave://settings/autofill disabled also
so double check it with your settings them if there any difference then apply them one by one till you get the one that we could missed
try this setting on the new profile you created so you did not miss with your old profile
the only differeance between me and you after apply those settings that i am using linux and you use windows
hope that help and have a nice day
