STM32WB55 issue with BLE Connection

Hi,

Everything was working fine with my stm32wb55 until it suddenly decided to stop working. Now when I tried to upload the example firmware for ble p2pserver and connect to the web application provided by stm, i am able to connect, but the web application shows data throughput for a second and then the page reloads. I tried erasing the chip, and reuploading the wireless stack, but nothing seems to work. Any help with this would be greatly appreciated. Thank you.

Edit: i tried running the data throughput example and this is the serial output i was getting:
