Solved
Hello all,
For everyone that came across this issue, for "Launch STM32CubeMX", "Launch STMCUFinder", you have to set the executable path not only the path of the folder, it should be something like this for windows:

And something like this for mac:
Home\xx\STMCUFinder\STMCUFinder
Home\xx\STM32CubeMX\STM32CubeMX
Hope that helps!
