Did you set a breakpoint in your application before starting the debug session?
If yes, you should add a breakpoint while debugging as mentioned in the errata sheet Known issues.

"If the Application context contains any break point even if it is disabled, the debug session will not start.

Workaround:

Therefore, any break point needs to be added while debugging and after the execution of this instruction “retr = MapMemory();”.

This is why we set the breakpoint at JumpToApplication instead of main in the startup configuration."

Have you seen this new (yesterday afternoon) Knowledge Base article:

How to connect the STM32N6 using STLINK and serial interface

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.
