STM32WB50 || Error- undefined reference to lpuart1_irqhandler

Empty code initialized peripherals(UART,SPI) code generated by STM32CubeIDE give error undefined reference to lpuart1_irqhandler at compile time.

In stm32wb50 only UART, SPI ,I2C & RF communication channel available.

Startup file has lpuart1_irqhandler , which is wrong .

if I can remove that line(line 197) from startup file it compile and run properly otherwise not.

What I do?

At the bottom of the file, a bunch of those symbols are defined as weak references to Default_Handler. Add this one as well:

 .weak LPUART1_IRQHandler
 .thumb_set LPUART1_IRQHandler,Default_Handler

Appears to be a bug in the STM32CubeWB repository:
