Duplicate build artefacts with numeric suffixes

[CTapp.1]

Why do I sometimes get duplicated build artefacts with numeric suffixes. For example:

This affects everything in the output folder (.elf file, .list file, ...).

I have to manually remove them, as "Clean" doesn't (they aren't part of the build).

Hello @CTapp.1 

For further investigation of the issue, could you please add more information about the version of STM32CubeIDE, the toolchain version, and attach your project if possible?

BR,

And even worse, those duplicates use spaces in their file names.

This is with version 1.18.1 on macOS, but I have seen it with other versions (including 1.16).

Unfortunately, I am not able to share a project at this time that shows the issue - but I'll come back if I notice it with one that I can share.

Edited to add:

Toolchain version is 13.3 rel1 (but earlier ones were used with older IDE versions).
