Xiaomi ax3200 Failed Downgrade and SSH Disconnected

Hello, when downgrading my Xiaomi router ax3200 rb01 from version 22.03.5 to 22.03.4, the process took a long time. Unfortunately, after 20 minutes, I disconnected and reconnected the cable once, after that the panel and SSH are no longer connected! I even reset it but it didn't work

I used openwrt web panel for Downgrade
