Since macOS 15.4 Beta 2, my App Store has been unable to install or download any new applications; it can only download applications I have previously purchased.
It appears as follows: when I click 'Get,' the system spins to load and then returns to the initial state.
Upon checking system error reports, it seems there's an issue with AMSUIPaymentViewService_macOS [2113]. This problem persists despite changing credit cards or even removing all credit cards.
macOS 15.4 Beta 3 has not fixed this error.
