IDE keeps crashing?? (Failed to assign value 80037b1, to register 0)

Please help:

I have a developed pcb with an STM32WB55 on it.  I have been working with it for over a month with no issue.  I am using a Windows 11, with CubeIDE 1.12.0 and a STLINK-VSET3 that is plugged directly into the laptop (no hub).  The board when reflashed always use to load then sit at main() now however starting today after loading the board the code seems to now sit within

startup_stm32wb55rgvx.s

Reset_Handler:
  ldr   r0, =_estack

After hitting the "run" button a few times it goes to main but then produces the following error within the console:

Download verified successfully


Failed to assign value 80037b1, to register 0
Failed to assign value 2002fff8, to register 0
Failed to assign value 8001390, to register 0

I have tried this on a second working board and get the same results.  I have powered down everything (including rebooting windows) and then I power up the board, power up IDE, plug debugger in and clean project.  Sometimes this briefly works in that I load code and sit at main.c but other times it does not.  Even if it sits at main there is no guarantee when I hit run that it won't create the error.

Can someone please help as we are under urgency with code development......

Sincerely

Steve

I was having the same issue.  After removing all of the live expressions things started working again.  The STMCube32IDE is very fragile!
