I honestly struggle why religious dress is treated differently in the year 2025 than other dress. Why is there a difference?
Define "religious dress".
Even if you assert the burka is intrinsically linked with Islam since it's almost uniquely worn by Muslims, it is not, in and of itself, part of a religious dress any more than an abaya, niqab, or any other item of clothing that might commonly be worn by Muslims is, so you are essentially asking for a ban on a item of clothing on cultural grounds, not religious.
Even if you accept it is a religious item, then you are off down the path of banning overt displays of religiosity in public spaces, and even if you yourself do not want to go there, someone else is immediately going to draw exception to seeing crucifixes, dog collars, Kippah, so on and so forth, at which point the law becomes an ass because it's clearly discriminating against one particular religion and not applying the same standard to the others.
