STM32WB55 BLE : Unknown sys evt received on Init

A tricky one here,

Migrated the BLE_HearRateFreeRTOS to a keil FuSa project. Using uvision.

During the Init process, the first BLE event that I receive after programming is an " unknown sys evt" .

Trace :

11/03 09:58:21.646 #1 unknown sys evt received: d8

11/03 09:58:21.646 Raw bytes size : 3, data:  c8 d8 00

After I press the reset button, and run the program again everything works fine.

 Using the STM32WB55.
