Having issue with change target MCU in MX

I have a project that was using an STM32WB55RG. I copied & pasted this project in Cube then opened up the IOC in MX & managed to retarget to an STM32WB55GC. But I now notice that the original project has also been retargeted.

So I tried to retarget it back to an STM32WB55RG in MX but the pinout compatible dialogue just hangs at 75%, see below. So what are my options here? Do I have to open up a new project from scratch & abandon my retargeting via MX?

Hello ​@NicRoberts 

The issue is reproduced with STM32CubeMX 6.13.

I suggest that you use the last STM32CubeMX version 6.18

Thanks

 Hello ​@NicRoberts 

Let me thank you for posting.

I reproduced the behavior described using the last STM32CubeMX 6.18 and the issue is not reproduced by my side.

For more investigation, could you please provide your Ioc.File.

 

Thanks.
